Answer:

see below

Explanation:

y +1=2(x + 7)

This equation is in point slope form

Let's put the equation in slope intercept form

Distribute

y+1 = 2x +14

Subtract 1 from each side

y+1-1 = 2x+14-1

y = 2x+13

This is in y= mx+b where m is the slope and b is the y intercept

The slope is 2 and the y intercept is 13
