Question

Graph the linear equation y = −x − 7 by plotting points.

Answer 1

Answer:

A straight line through  ( 0 , − 7 )  and  ( 7 , 0 )

Step-by-step explanation:

x − y = 7

can be rewritten as y= x −7

This is the equation of a straight line of slope = 1 and y-intecept of  − 7

Since the graph is a straight line only need two points to plot it.

For simplicity, I will choose  

( 0 , − 7 )  and  ( 7 , 0 )

The graph of the line is shown below.
