Question

Which is an equation in point-slope form for the given point and slope?



Point: (–3, 7); Slope: 4









A.

y – 7 = 4(x – 3)








B.

y – 7 = 4(x + 3)








C.

y + 7 = 4(x + 3)








D.

y + 7 = 4x – 12

Answer 1

point slope form is : y - y1 = m(x - x1)

slope(m) = 4
(-3,7) x1 = -3 and y1 = 7
now just sub

y - y1 = m(x - x1)
y - 7 = 4(x - (-3)
y - 7 = 4(x + 3) <=== here you go, in point slope form
