Vikentia [17]
Slope of line j;
m=\frac{change in x}{change in y}
m=\frac{6-1}{-3--6}
m=\frac{5}{3}
Parallel lines have equal gradients;
So, 
y=mx+c
y=5/3x+c
Replacing for x and y;
-1=5/3(15)+c
-1=25+c
c=-26
y=\frac{5}{3} x-26

Write an equation of the line that is parallel to the given line and passes through the given point.
castortr0y [4]
The points it gives you are y intercepts, and because you’re trying to find lines parallel- the only thing that changes for the equation is the y intercept.

1) y=2x+4
2) y=-x+7
3)y=-8x-2

Determine whether each scale factor produces an expansion or a contraction under a dilation of the original image
blondinia [14]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image

If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image

so

<u><em>Verify each value</em></u>

1) -4

\left|-4\right|=4

4> 1

therefore

The dilation produces an expansion of the original image

2) 0.25

\left|0.25\right|=0.25

0.25 < 1

therefore

The dilation produces a contraction of the original image

3) -2/3

\left|-2/3\right|=2/3

2/3 < 1

therefore

The dilation produces a contraction of the original image

4) 2.3

\left|2.3\right|=2.3

2.3 > 1

therefore

The dilation produces an expansion of the original image
