Priya writes the equation y = -1/2x - 7. Write an equation that has: 1. exactly one solution in common with Priya's equation

2. no solutions in common with Priya's equation

3. infinitely many solutions in common with Priya's equation, but looks different than hers

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.

after simplifying it i got: -36.25 as my answer. hope that !

the answer is d on edge
