Multiply each equation by a constant that would help to eliminate the y terms.
2x-5y=-21
3x-3y = -18
What are the resulting equations?
6x-15y =-63
-15x+ 15y = 90
o
Ex-15y = 63
- 15x+ 15y = 90
Ex-15y =-63
- 15x+15y =-90

y=mx+

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
