Question

Write the equation of a line that is parallel to y = -3x + 3 and contains the point (1,-2). Write the equation in slope intercept form.

Answer 1

a line that is paralell would have the same slope, so the slope is -3, but different y intercept


so y=-3x+b
subsitte 1 for x and -2 for y
-2=-3(1)+b
-2=-3+b
add 3 to both sides
1=b

the equationis
y=-3x+1
