The equation a = 50m + 100 represents the amount of money in Malorie’s bank account as a function of time, in months. The table shows the amount in Katina’s bank account for a period of several months. Month 0 1 2 3 4 5
Katina's Bank Account 200 220 240 260 280 300

A. How much money is in Malorie’s bank account when Katina has $280 in her account? Show your work.

B. Whose account changes at a greater rate? Show your work.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the answer

b. they are parallel and will never intersect.

heyyy
