Question

Write the equation of a line containing the point (4, -1) and having slope 12.

Group of answer choices

y=12x+3.5




y=12x−3




y=12x−1

Answer 1

y = 12x - 49

Explanation:

Since we are given the slope(m) and a point (x,y), we can use the point-slope equation to solve for the equation of the line.

y - y = m(x - x)

Plug in the given numbers

y - -1 = 12(x - 4)

Minus a negative becomes a positive

y + 1 = 12(x - 4)

y + 1 = 12x - 48

y = 12x - 49
