Answer:
y = 4x + 5
To find the slope do :
21 - (-3)
4 -(-2)
That will equal :
24 simplified : 4
6
Take your slope and one of the points and plug it into y = mx + b
That will look like: (21) = 4(4) + b
21 = 16 + b
Subtract 16 -16 -16
on both sides
This is your y-int: 5 = b
Put the slope and y-int into the equation
And this is your answer: y = 4x + 5
