Answer:
A) 
Step-by-step explanation:
Point-slope formula.

Given.
Slope (m) = 3
Points (x, y) = (2, 1)
Answer:
y=-2x-7 D
Step-by-step explanation:
Answer: a) -13/16
Step-by-step explanation: Start by setting equations equal and rearrange X^3 - x^2 + 1 = 0. Visual inspection of graph shows x between -1 and -1/2. Start with x = 3/4 plug in and calculate: just a little too small. Try going halfway towards -1: x =-7/8 Plug in and the answer is very far from 0. Go halfway back towards -3/4: -13/16 and the equality is very close.
For a line to be parallel, it must have the same slope as the first line so the slope of a parallel line would be -6.
