Question

Select the equation of the line parallel to the equation y=-3x-5 that passes through the point (1,2)

Y=-3x+5
Y=-3x+6
Y=-3x-3
Y=3x-1

Answer 1

the answer is y=-3x+5
since it's parallel, the slope is the same. so m=-3
use point slope formula y-y1=m(x-x1) and plug in the slope and the point
y-2=-3(x-1)
y-2=-3x+3
y=-3x+5
