Answer:
yes
Step-by-step explanation:
Find slope (y2-y1)/(x2-x1)
Pick any two points on line
(1,15) and (2,25)
(25-15)/(2-1) = 10/1, slope is 10 (rate of change)
Y = 10x + b
15 = 10 + b
The y intercept would be 5
K is less than -10, you would divide by -9 on each side and when you divide by a negative then you turn the sign around.
She has enough money, the total will be $95
you add 10+10+75, to get $95
