The ratios are equivalent because 30 * 4 is 120 and 12 * 4 is 48
Answer: the answer is a
Step-by-step explanation: learned about it in 9th grade
Triangle will be formed. base = 5-(-3)= 5+3=8 ( lies on the X axis ) height = 4 Area of triangle = base *height/2 =8*4/2= 16 sq. units

You can reword the two equations as:
-5x-y=15 (Divide original value by 3)
-2x+6y=6
Then use elimination to find x:
-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)
-2x+6y=6
You're left with:
-32x=96. Which can then be solved to find x which is -3.
Then plug back in
-2x+6y=6
Now to: -2(-3)+6y=6.
Which reduces to 6+6y=6. So y=0.
To graph them, just reword the equations (yes once again) so that y is in front.
y=-5x-15 and y=(1/3)x+1
