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.
