Mark owes sally 85.00$ he finds 14 friends to help him pay her back. How much does each friend need to pay? (This includes mark)
Suppose the line is y=mx+b
when x=3, y=15, so 15=3m+b
when x=-1, y=-13, so -13=-m+b
solve the system of these two equation, you get m=7, b=-6
so the linear equation is y=7x-6
The answer is falseeeeeeeee
Answer:

Step-by-step explanation:
90° - 35° = 55°
Answer:
rate of change is 4.
Step-by-step explanation:
rate of change is the slope, so, pick any two relations given to us in the table.
(-3, -14) and (-1, -6).
slope = y2 - y1/ x2 - x1
slope = -6 - (-14)/-1-(-3)
slope = 8/2 = 4.
the rate of change is 4.
