Question

A line passes through the point (3, -12) and has slope of 7.

Answer 1

Answer:

y = 7x - 33

Step-by-step explanation:

Using a given point and slope, we need to use point-slope form.

$y - y_1 = m (x - x_1)$

m= 7 (slope)

$x_1$ = 3 (x value from given point)

$y_1$ = -12 (y value from given point)

$y - y_1 = m (x - x_1)$  

$y - ( -12) = 7(x -3)$       Now we Substitute values in

$y + 12 = 7(x -3)$    Double negative with - (-12) makes 12 positive

$y + 12 = 7x -21$       Use distributive property for 7(x -3)

$y = 7x -33$           Subtract 12 from both sides
