Explanation:
When dilating with respect to the origin, any point of the form (x,y) moves to (kx, ky) for some real number k. The k is the scale factor.
Point C is at (-2,2). It moves to C ' (-5,5)
The jump from x = -2 to x = -5 is "times 5/2" since kx = (5/2)*(-2) = -5
The same scale factor is used when going from y = 2 to y = 5.
Both x and y coordinates are multiplied by 5/2 to move from (-2,2) to (-5,5)
Therefore, the dilation rule we use is

Answer:
Step-by-step explanation:
The Slope-intercept form of the equation of the line is:
m: is the slope.
b: the intersection of the line with the y-axis.
The equation of the line has:
If both lines are parallel, then their slopes are equal. So the slope of the other line is:
To find "b", substitute the given point and the slope into and solve for "b":
Then the equation of this line is:
