Determine which of the following equations, when graphed, intersect at the point (4, 0). Select all that apply.
- x - y = 4
x - y = 4
2 x + y = 7
2 x + y = -7
x + y = 4
2 x - y = 7

x - y = 4  

x + y = 4     hope tis helps

Step-by-step explanation:

Substitute x=4 and y=0 in every equation. If both sides of the equal sign are equal, (LS=RS, left side equals right side) then the graph intersects at (4,0).

- x - y = 4  

- (4) - 0 = 4

-4 = 4

LS≠RS

x - y = 4  

4 - 0 = 4  

4 = 4

LS=RS

2 x + y = 7  

2(4) + 0 = 7  

8 = 7

LS≠RS

2 x + y = -7  

2(4) + 0 = -7  

8 = -7

LS≠RS

x + y = 4  

4 + 0 = 4  

4 = 4

LS=RS

2 x - y = 7

2(4) - 0 = 7

8 - 0 = 7

8 = 7

LS≠RS

Only x - y = 4  and x + y = 4  intersect at (4, 0)

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
