Question

Use the point in the graph to find the equation of the line in point-slope form.

A) y + 20 = 2(x + 80)
B) y + 20 = 1/2(x + 80)
C) y − 20 = 2(x − 80)
D) y − 20 = 1/2(x − 80)

Answer 1

The answer is C

Explanation:

Answer 2

C)
`y - 20 = 2(x - 80)`

Explanation:

According to the Point-Slope Formula,
`y - y_1 = m(x - x_1)`, all the negative symbols give you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT signs.
