Question

Which ordered pair is a solution to the linear equation -3x+2y=4?

substitute 0 for x to find the y-intercept
substitute 0 for y to find the x intercept
find the x intercept and find the y intercept

Answer 1

Explanation:

Substitute x= 0

-3(0) +2y = 4

2y = 4

y = 4/2

y = 2

and then substitute y=2 into eq.

-3x +2y = 4

-3x +2 (2) = 4

-3x +4 = 4

-3x = 0

3x = 0

x = 0

Check result: x = 0 y = 2

-3x + 2y = 4

-3 (0) + 2 (2) = 4

0 + 4 = 4

4 = 4 therefore x and y correct.

Answer 2

-x+y-3z+4w=6^"dfv
+xd-y+23z=0
so x=1 and y=3
