![]() Let’s run through a couple of examples involving y-intercepts and x-intercepts. Real World Examples of X and Y Intercepts After reading the formulas, you might wonder how this applies to real life. If you use the intercept form calculator, you will see it displays both values. Y = 2x – 1 Finding X and Y Intercepts You find the x-intercept value when the x crosses through the straight line. You can use x₂ and y₂ instead of x₁ and y₂Ĥ.Ĝonstruct the slope intercept form with the values For the example, it’s:Ģ.ğind the slope with the slope intercept formula Write down the first point’s coordinates. You will need the two points that go through your line. Now that you know the slope, get the y-intercept by substituting it into the equation (first or second.)ī = y₁ - x₁ (y₂ - y₁) / (x₂ - x₁) How Do You Find the Equation of a Line? In the slope intercept form, find the line’s equation. Subtract the first equation from the second.ģ.ĝivide the sides of the equation by (x₂ - x₁) to identify the slope. Substitute the two points’ coordinates in the equation.Ģ. What you don’t know is the slope (m) and the y-intercept (b).ġ. The first will be ( x1, y1), and the second ( x2, y2). The Slope-Intercept Formula By now, you’ll want to cut to the chase and find the slope-intercept form of a linear equation. You will learn more about that below, including the importance of this rule in linear equations. In a linear equation, you find it by substituting x for 0 (x = 0). ![]() It crosses the straight line at the y-axis. If the difference in x is positive, y increases. It determines any changes in y due to a fixed shift in x. The slope part refers to a gradient or incline. These values come in handy for linear interpolation. You learn the slope is m and the y-intercept is b. The slope-intercept form has an equation that looks like y = mx + b, as mentioned before. A linear equation describes a straight line, using a slope-intercept form to express it. You will see an x and y, but you won’t see an x2 or y2. Straight line equations, or linear equations, have no terms with exponents. You can use a parabola calculator to learn more about that side of things. With this slope intercept form calculator, you work with the straight line. The relationship of a straight line (with b and m as numbers) are y = mx + b. An example of that would be the quadratic function – y = x2 + x, which is a parabola. What goes with x determines the line you have. Both are points that contribute to that line. Definition of Slope-Intercept Form You can describe a line in a flat plane as having an X and Y axis. Read on to discover more about slope intercept formulas, linear equations, and more. ![]() ![]() This tool lets you find the x and y-intercepts and the coefficients of the slope. a, b and c can be entered as integers, fractions or numbers with a decimal point as shown below.įor lines of the form ax = c (b = 0), the slope is undefined.Do you need to find an equation for a line that passes through two points? It might seem challenging, but a slope intercept form calculator can help. Use Slope Intercept Form of a Line Calculatorġ - Enter the coefficients a, b and c and press "Slope Intercept Form". The importance of the slope intercept form of a line lies in the fact that the slope m and the y intercept B of the line are easily identified and here are the steps to follow:ġ) Solve the general equation a x + b y = c for yįor b not equal to zero, we divide all terms by the coefficient b.Ģ) Compare the above equation to the slope intercept form y = m x + B and identify m and B asįind slope and the y intercept of the line given by the equation 2 y + 3 x = 6Ĭompare the above equation to the slope intercept for y = m x + B to find Into the slope intercept form y = m x + B.
