I think the answer to 14 is J
Answer:
y=10x+50
Explanation:
The line starts at point (0,50) which is the y intercept (how much he gets paid to visit house).The line crosses points (10,150) and (20,250) and the slope of these points are 100/10 which when simplified equals 10x which is how much money he gets paid by the hour(x=hours) so y=10x plus the y intercept y=10x+50
(11+21)-(3-101)=(11+21-3-10=(11-3)+(21-101=8-18=53
Answer is B, -6 - -6 = 0 7-3=4 0/4 =0
A’s slope has no meaning
C’s slope is 1
D’s slope is -14/-18
