Answer: -6.5x+4.4
Step-by-step explanation:
Answer:
y = 1x + 7
Step-by-step explanation:
y = 1x + b
4 = 1(-3) + b
4 = -3 + b
7 = b
Answer:
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.

Answer:
See below.
Step-by-step explanation:
a) y = 2x + 3 and y = -2x + 11
One solution. They are straight lines with different slopes, so they will intersect at some point.
b) y = x + 2 and -2x + 2y = 4
-2x + 2y = 4 can be rearranged to 2y = 2x +4 and then y = x + 4
Both lines have the same slope, 1. They are parallel and will never meet. No solutions.
c) y = x - 3 and y = x + 6
This has the same answer as c. Parallel lines (both have slopes of 1.). They will never meet: no solutions.
d) y = 7 and y =3x-5
One solution. Straight lines with different slopes (3 and 0) so they will cross at one point. [At (4,7)]
e) y = -4x and y = -4x - 1
Same slopes. There are no solutions.
