![]() ![]() If you need to calculate the slope using two points, use slope calculator. Step 2:Write the slope form equation and place the values. To find equation of a straight line with slope and y-intercept, follow the example below.įind the Straight line equation if y-intercept is 6 and slope is 4. Y = mx + c How to find the slope intercept form (equation of a straight line)? In UK, variable c is used to represent y-intercept. The equation of slope intercept varies in USA and UK. x, y represents the x and y coordinates,.The slope intercept equation can be represented as: Slope intercept is a form of linear equation that can be used to find the equation of a straight line with y intercept and slope of line. Remember that the y intercept refers to the point where the given line intercepts with the y-axis.Slope intercept form calculator is an online tool that is used to find slope intercept form (equation of line) using two points, y-intercept, or one point and slope. Finally, write the value you obtained as a coordinate point.Starting with 4 = 2(3) + b, rearrange the equation in a few steps: Therefore, all you have to do is rearrange the variables to find the y intercept. As you can see, b is the only variable which remains in your equation. The next step to take is to solve for b or the y intercept.Substitute these values for the x and y values in the equation: 4 = 2(3) + b. In our example, the coordinates of the point of the line are (3,4) which means that x = 3 and y = 4. As long as you have the values of the coordinates of any single point on the given line, you can substitute these values for the y and x coordinates in the equation. Now it’s time to replace the y and x coordinates of your point.Therefore, when you’re writing the slope-intercept equation, write the slope of the line in place of m. In this equation, substitute the value for the slope.In this form of the equation, the m variable refers to the slope while the b variable refers to the y intercept. ![]() Remember that you can write any given straight line as an equation: y = mx + b.
