Question 10 (5 points)

(01.05)
What is the equation in point-slope form of the line passing through (-1, 3) and (1,7)? (5 points)
a. y-7 = 4(x - 1)
b. y-7 = 2(x - 1)
с. y-3 = 2(x - 1)
d. y-3 = 4(x + 1)

Answer 1

Hey there!

Slope: 7-3/1-(-1), which is equal to 4/2, or 2.

Point slope: y-7=2(x-1)

So choice B is correct.
