Answer:
not a function because the points' x-values repeats
Step-by-step explanation:
Step-by-step explanation:
= 2x - 9y + 4x + 11y
First of all combining like terms
So
= 2x + 4x - 9y + 11y
= 6x + 2y
Now putting values
= 6 (-2) + 2(4)
= - 12 + 8
= - 4
3x-10+2x=115
5x-10=115
5x=125
x=25
m<b=3(25)-10=65
m<C=2×25=50
