7.) (x, y) —> (1/2*x, 1/2*y)
The second box to the left side
(0,-5) is the y-intercept
Answer:
x=9
Step-by-step explanation:
subtract 22 from both sides, simplify 3x = 10x-63, subtract 10x from both sides of the equation, simplify -7x = -63, divide both sides of the equation by the same factor -7x/-7 = -63/-7, then simplify
-3x-2y=30
-2y=3x+30
y=-3/2x-15
the answer is y=-3/2x-15
