What is the equation for the (graph) line? ( )

y = 8x

Step-by-step explanation:

The equation for any straight line is y= bx + c

b is equal to the gradient, meaning you have to draw a triangle (like in the image above)

You then divide 8 by 1 to get you the gradient which is what goes in front of x.

c is the y intercept which is where the line crosses into the y axis. In this case it is zero.
