Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3

Ray Of Light [21]

Answer:

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (7, - 2 ), thus

y - (- 2) = - 3(x - 7) , that is

y + 2 = - 3(x - 7) → B

Answer:

x = -12

y = 3

Step-by-step explanation:

$1/2x + 6(x+15) = 12\\1/2x + 6x + 90 = 12\\6\frac{1}{2} x + 90 = 12\\6\frac{1}{2} x= -78\\x = -12$

$y = x + 15\\y = -12 + 15\\y = 3$
