Find the equation of the line graphed below. Write the equation in the form y=mx+b and identify m and b.

The slope appears to be 8/3, and the y-intercept appears to be 1. So the equation is y=8/3x+1.

How did you get 8/3 as the gradient here?

 

This is incorrect as the gradient is 1/4

Using rise/run, it can be seen that the gradient of this line is 1/4.

 

The labelled y intercept is the value of b, thus 1

 

Therefore the equation of this line is equal to:

 

y=1/4x + 1
