Question

What is a slope of a line parallel to the line whose equation is Y - X = 5

A) -1
B) 1/5
C) 1
D) 5

Answer 1

C

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y - x = 5 ( add x to both sides )

y = x + 5 ← in slope- intercept form

with slope m = 1

Parallel lines have equal slope, thus

the slope of a parallel line is m = 1 → C
