Does the graph of the equation y = 7 - 2x increase or decrease? A) decreases because the x values decrease from left to right B) decreases because the y values decrease from left to right

y=mx+b
m=slope=rise/run
if slope>0, then it increases
if slope<0, then decreases because it is going down

y=7-2x
y=-2x+7
-2<0
decreasing
because the y values decrease from left to right
the x values always increase if you go from left to right

B is the answer

The graph of the given equation decreases because the y values decrease from left to right. So, option B is correct.

It is given that,

The linear equation is [tex]y=7-2x[/tex].

Explanation:

Substituting [tex]x=0[/tex] in the given equation, we get

[tex]y=7-2(0)[/tex]

[tex]y=7[/tex]

Substituting [tex]x=1[/tex] in the given equation, we get

[tex]y=7-2(1)[/tex]

[tex]y=7-2[/tex]

[tex]y=5[/tex]

Plot the points (0,7) and (1,5) on a coordinate plane and connect them by a straight line.

From the graph of [tex]y=7-2x[/tex], it is clear that the graph of the given equation decreases because the y values decrease from left to right. So, option B is correct.
