Answer:
Step-by-step explanation:
1) First, find the slope of the line. Take two points the line intersects and use them for the slope formula, . We already know the line intersects (-4, -2). Just choose any one of the points you can see the line intersecting (in this case, I chose (0,3)) and plug in its values, too. Then solve:
So, the slope is .
2) Now that you have the slope, plug in values for the point-slope formula, . In order to write a linear equation with it, the , , and have to be substituted for with real values. The represents the slope - which means that we should place there. The and represent the x and y values of a point - and the questions wants us to use (-4, -2), so substitute -4 for and -2 for :
Thus, the answer is .

Answer:
8x + 24
Step-by-step explanation:
Given photograph length L = 7" and width W = 5"
Also that the frame is 2x" longer and 2x" wider
hence,
new length = ( 7 + 2x) inches
new width= ( 5 + 2x) inches
Hence perimeter of frame,
= 2 x ( new length + new width)
= 2 [( 7 + 2x) + ( 5 + 2x)]
= 2 (4x + 12)
= 8x + 24 (Answer)
This is problem of ratio and proportion. to solve this, fisrt is calculate the convertion factor.
so the house is 30 feet in actual and 4 in wide on drawing
30 feet / 4 in = 7.5 feet / inso in every inch in the drawing is equivalent to 7.5 feet on actual.
1.2 in ( 7.5 ft/ in) = 9 ft
1.6 in ( 7.5 ft/ in) = 12 ft
