20 points margaret earns $15.25 an hour working at a record store and is paid every week. she takes $50 from each paycheck and puts it in her savings account. she spends the remainder of her paycheck.

part a: identity the variables y, m, x, and b in the given situation. explain each variable.

part b: write the linear equation that represents the given situation z

part c: explain how the equation from part b can be used in relation to the given situation.

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.

answer:
