First, the equation needs to be put into slope-intercept form, which is y = -4/5x + 7/5. Then, you need to know what parallel and perpendicular lines are. REMEBER, parallel lines have the same slope, and perpendicular lines have slopes whose product equal -1. You just need to substitute. For the parallel line, -2 = -4/5(4) + b, and b = 6/5, so y = -4/5x + 6/5. For the perpendicular line, the slope is 5/4. Now substitute. -2 = 5/4(4) + b, and b = -7, so y = 5/4x -7.
Answer:
im kind of rusty on this math but i think the equation would be y=-5x+b i forgot how to find b tho :( im sorry
16x+60y
16(.75)+60(.25)
12+15=27
maria would charge $27 for this necklace
I believe the answer is the 64 ounce container that is $3.20. the unit price of it was 0.05 while the other one was 0.055
