ANSWER

y = 5x  - 11

EXPLANATION

The given line passes through:

(3,4) and (2,-1).

The slope is given by:

m =  \frac{ - 1 - 4}{2 - 3}

m =  \frac{ - 5}{ - 1}  =  5

The equation can be found using

y-y_1=m(x-x_1)

We plug in the point and slope to get:

y - 4 = 5(x - 3)

y - 4 = 5x  - 15

y = 5x  - 15 + 4

y = 5x  - 11

This is the slope-intercept form
