Step-by-step explanation:
Answer:
y = 6x +2
Step-by-step explanation:
It is useful to start with the point-slope form of the equation for a line when you are given a point and a slope.
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -(-22) = 6(x -(-4))
y +22 = 6x +24 . . . simplify
y = 6x +2 . . . . . . subtract 22
