Question

Use the double intercept approach to find the graph of –1 = –y + x. A. B. C. D.

Answer 1

Intercepts at (-1, 0) and (0, 1).

Explanation:

The double intercept form for the equation of a line is

ax + by = 1

-1 = -y + x

y = 0

x = -1 Multiply each side by -1

-x = 1

The x-intercept is at (-1, 0).

=====

x = 0

-1 = -y Multiply each side by -1

y = 1

The y-intercept is at (0, 1).

=====

The graph (see below) is a straight line passing through the points (-1, 0) and (0, 1).
