Slope = 5
y = mx + b
2 =5(4) + b
b = 2 - 20
b = -18
<span>point-slope equation
y - 2 = 5(x -4)
</span><span>slope-intercept equation
y = 5x - 18
standard form
5x - y = 18</span>
I think it’s 3.. maybe check with another answer to see if I’m correct or not.
19.2 is the answer. you add them up then estimate to find you answer.
