Question

Question 10 (5 points)
Which is the point-slope form of an equation for the line that passes through (0, -5)
with slope 2?
a) y = 2x - 5
Ob) y = 2(x + 5)
Oc) y - 5 = x - 2
d) y + 5 = 2x

Answer 1

I think the answer is A

Answer 2

Answer:

y + 5 = 2x

Step-by-step explanation:

Use the point-slope form of the equation of a straight line, y  - k = m(x - h).  In this problem, the given point is (0, -5), meaning that h = 0 and k = -5, and the slope is m =2.  Therefore,

y - k = m(x - h) becomes y + 5 = 2(x - 0), or:

y + 5 = 2x     This matches Answer d.
