Answer:
y=2x
Step-by-step explanation:
Slope (m): the formula for slope is y2-y1 over x2-x1 so it will be 2-(-2) over 1-(-1) and the result will be 2.
Y intercept: The Y intercept is 0 as shown in the graph

Answer:
a. 1.5 inches wide.
Step-by-step explanation:
If the width of the frame is x the length of the picture + frame = 2x + 12 and the width is 2x + 9 , so we have the following equation:
The total area = (2x + 9)(2x + 12) = 180
4x^2 + 24x + 18x + 108 = 180
4x^2 + 42x - 72 = 0
2(2x^2 + 21x - 36) = 0
2 (2x - 3 )(x + 12) = 0
x = 1.5 , -12 (we ignore the negative root).
