Question

Which choice shows +=7

Answer 1

Answer:

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

Step-by-step 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
