Question

what is the equation of the line in standard form that passes through the point (-2, -3) and is parallel to the line y= x + 9
a)x - y = 1
b) x + y = 1
c) x - y = -5
d) x + y = 5

Answer 1

just move y to the right and 9 to the left.
you have the other in the standard form
so you can narrow it down to a and c right away. chance both in to slope intercept for.
a. y=x-1
start at (0,-1)
down left 1
-1,-2
down left down 1
-2,-3. Thus your choice is a
