Use subsititution to solve each system of equations. [y = 4x] [3x - y = 1] *
25 points
(-1,-4)
(1,-4)
(-4,-1)
(4,-1)

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
