Question

Which choice shows +=7

x
+
y
=
7
in slope-intercept form and the correct graph of the equation?

Answer 1

y=-x +7 is the slope-intercept form and the graph is shown in the attachment.

Explanation:

The given equation is

`x + y = 7`

We solve for y to get:

`y = - x + 7`

This is now of the form, y=mx+c

This is called the slope-intercept form.

Since the slope is negative, the graph slopes backwards. Also the y-intercept is 7, so the graph will intersect the y-axis at 7
