What are the coordinates of the image of point b, after the segment has been dilated by a scale factor of 3 with a center of dilation at the origin?
a. (–9, 9)
b. (9, –9)
c. (–1, 1)
d. (1, –1)

A

Step-by-step explanation:

Since the dilatation is centred at the origin, then each of the coordinates of B are multiplied by the scale factor of 3

B(- 3, 3 ) → B'( 3 × - 3, 3 × 3 ) → B'(- 9, 9 ) → A

answer: x=3 and y=4

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
