Answer:
7. Slope = -5
Y-intercept = -3/4
8. Slope = 1/4
Y-intercept = 5
Step-by-step explanation:
y = mx + b
Slope = m
Y-intercept = b
Answer:

Step-by-step explanation:
Set the equations equal to each other: 25x+45=15x+14
Solve for x: 10x = -31
Solve for x: x=-3.1
Plug the x value back into one of the equations to find the value of y:
y = 15 (-3.1) +14
y = -32.5
15/26 * 4/9 = 60/234 = 10/39
X intercept: (7/6, 0)
y intercept: (0, -7/3)

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

So, in conclusion Harry did earn $6 in interest for every $100
