Question

Given the equation y + 4 = 3(x - 2) in point-slope form, identify the equation of the same line in standard form. (2 points)

a
\large -3x+y=-10

b
\large -3x-y=-10

c
\large 3x-y=10

d
\large 3x+y=-10

Answer 1

c

Explanation:

y + 4 = 3(x - 2)

Distribute the 3 on the right side.

y + 4 = 3x - 6

Subtract y from both sides.

4 = 3x - y - 6

Add 6 to both sides.

10 = 3x - y

Switch sides.

3x - y = 10

Answer: c
