Question

A line passes through the point (-4,-20) and has a slope of 3. Write an equation of the line satisfying the given conditions. Write the answer in slope-intercept form

Answer 1

9514 1404 393

Answer:

y = 3x -8

Explanation:

The point-slope form of the equation of a line can be a useful place to start.

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y +20 = 3(x +4) . . . . with given numbers filled in

y = 3x +12 -20 . . . . eliminate parentheses, subtract 20

y = 3x -8 . . . . . . . . slope-intercept form
