Question

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

Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)

Answer 1

Answer: y-9=2(x-5)

Step-by-step explanation: The point (5,9) satisfies the equation:

y-9=2(x-5) for (5,9)?

9-9=2(5-5) ?

0 = 0 YES

Slope of 2? Rewrite:

y-9=2(x-5)

y = 2(x-5)+9

The slope is 2 YES
