Final answer:

Option C) y = -x + 8 is in Slope-Intercept Form with a slope of -1 and y-intercept of 8.

Step-by-step explanation:

The Slope-Intercept Form of a linear equation is given by:

=

+

y=mx+b

where:

m is the slope of the line,

b is the y-intercept (the point where the line crosses the y-axis).

Let's examine the given options:

A)

6

=

2

+

7

6=2x+7y - This equation is not in slope-intercept form.

B)

4

=

2

+

15

4x=2y+15 - This equation is not in slope-intercept form.

C)

=

+

8

y=−x+8 - This equation is in slope-intercept form (

=

+

y=mx+b) where the slope

m is -1 and the y-intercept

b is 8.

So, the correct answer is option C:

=

+

8

y=−x+8.
