Question

Write the equation of the line that is parallel to the line y = −3x + 12 and passes through the point (−1, 6).

Answer 1

y = one thirdx + 7

y = −3x + 3

y = one thirdx + 3

y = −3x + 7

these are the choices

Answer 2

same as the one before, just that, parallel lines have EXACTLY the same slope, so the slope of => y = −3x + 12
is -3
so any parallel line to it will also have a slope of -3
so => \(\bf \large y-y_1=m(x-x_1)\)
m = slope
(-1, 6) = \(\bf \large (x_1, y_1)\)
