x = interest paid altogether

400 + 400(0.175) = x

The 400 comes from the average balance. 400(0.175) comes from the interest she has to pay each month. 1.75% as a decimal is 0.175. It's multiplied since she pays 1.75% of the average balance.

Find the slope of (-9,18),(-13,5)
Jet001 [13]

Answer:

3.25

Step-by-step explanation:

The slope formula is slope = y2 - y1 / x2 - x1 and the variables are found by assigning them with their corresponding values. Here, x1 = -9, x2 = -13, y1 = 18, and y2 = 5. Next, substitute these values in and get 5 - 18 / -13 - (-9). This can fully simplify to 13 / 4 or 3.25.
