Equation of a line

Equation of a line To find the equation of a line, you need two pieces of information: The SLOPE The y-intercept Slope....how steep the line is y-intercept....where it crosses the y axis Write the equation in this order: y = mx + b m=slope b=y-intercept So...if the slope is 5 and the y intercept is 6, the equation is: y = 5x + 6 slope =5/1 = 5 y=5x+6 1 5 6 y int. y=2x-3 -3 1 2 2 -2 4 -4 2 -2 4 -4 6 -6 y=-2x+3 3 -2 1 Now it's time for you to try. I've turned on the right/wrong counter at the top right so you can see if you are correct. |
