Question

Which graph is the solution to this system y-4x=-1y+x=4

Answer 1

First, let's find the x and y intercepts

In the first equation

y - 4x = -1

Put x =0

y= - 1

(0, -1)

Put y=0 and the n solve for x

0 - 4x = -1

-4x = -1

x=0.25

(0.25 , 0)

The points for the first equation is (0, -1 ) and (0.25, 0)

Next is to find the intercts for the second equation

y + x = 4

put x=0

y = 4

(0, 4)

Put y =0

0 + x = 4

x = 4

( 4, 0)

The points for the second equation are;

(0, 4) and (4, 0)

Below is the graph
