Answer:
x=2 and y= -2
Step-by-step explanation:
Substitute y=x-4 in second equation
x-4=4x-10
get x terms on one side and numbers on other sides
4x-x=10-4
3x=6
divide 3 on both sides
x=2
substitute x=2 in y=x-4
y=2-4
y= -2
D
uses the the formula y=mx+b and m is the slope. b is the y intercept.
"Undefined" slope means the line is vertical, of the form x = constant. The constant is the x-value of the point the line goes through.
C) x = 2
K = 100/9, or approximately 11.111
