Question

What is the slope of a line parallel to 4x + y = -1?

Answer 1

A line parallel to 4x + y = -1 will have the same slope as the line 4x + y = -1.

Answer 2

what does that mean?

Answer 3

Do you know how to find the slope of the line 4x + y = -1?

Answer 4

no I do not.

Answer 5

The genral equation of a line is y = mx + b, where m is the slope.

So we will take our equation and solve for y:

4x + y = -1
Subtract 4x from both sides, we get
y = -4x - 1

so the slope is -4, the coefficient of the x-term.

Answer 6

So any line parallel to this line will also have a slope of -4.
