Question

Which choice shows +=7

Answer 1

Answer:

$y=-x+7$

The graph in the attached figure

Step-by-step explanation:

we have

$x+y=7$

This is the equation of the line in standard form

Convert to slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

Isolate the variable y

subtract x both sides

$x+y-x=-x+7$

simplify

$y=-x+7$

The y-intercept is the point (0,7)

Find the x-intercept

For y=0

$0=-x+7\\x=7$

The x-intercept is the point (7,0)

Plot the intercepts and join them to graph the line
