Question

Choose the equation of the line passing through the point (-3, 1) and parallel to y = -x - 4.
A.y = x + 2

B.y = -x - 2

C. y = -x + 4

D. y = x - 4

Answer 1

Parallel lines have the same slope. When you write the eq of a line as
y = mx + b, m is the slope. This eliminates two answers.

Answer 2

Since the given line has a slope od -1, the parallel line has to be y = -x + b.
To find b, insert the values of x and y of the given point into y = -x + b and solve for b.

Answer 4

Slope is a measure of the inclination of a line. It tells you how much the line tilts one way or the other. When you graph a line, a line can be horizontal, vertical, or diagonal. When it is diagonal, it either goes up to the right or up to the left.

Answer 5

The slope tells you exactly how th eline tilts. If two lines are parallel, they have the same slope.
