Answer:
x=21/5
Step-by-step explanation:
5x:9 = 7:3
Turn the ratios into fractions:
5x/9 = 7/3
Then cross mutiply
15x=63
x=21/5
You'd use the equation y2-y1/x2-x1
0-(-3)/-7-5 = 3/-12 = -1/4
So -1/4 would be the slope
m= -1/4
The shape is a parallelogram because the length of the sides based on the coordinates
It is definitely a. 9>5n
Because it say 9 is more than five times a number and if you have any questions just comment an I'll try to help! :) Hope I helped!
