Answer:
-1/2
Step-by-step explanation:
The slope of a line is given by
m= (y2-y1)/(x2-x1)
= (3-6)/( 4 - -2)
= -3 / (4+2)
= -3 /6
= -1/2
Answer:
y=2.13
Step-by-step explanation:
cross multiply
0.8/1.8=y/4.8
4.8*0.8/1.8
3.84/1.8
y=2.13
Answer: There are no like terms
Step-by-step explanation:
The distance from point Y to the y-axis is 4 units and the distance from point Z to the y-axis is 3 units, then the lelgth of the segment YZ is 4+3=7 units.
If <span>a scale factor is 3, then the length of Y'Z' will be 7·3=21 units.

P.S. In the added picture you can see trapezoid ABCD that was dilated by a scale factor 3 about the origin. This may help to understand that all linear values after dilation become multiplied by scale factor.
