So the easiest way to do this problem is to put your equation in linear form, meaning y = the rest of the equation.
I'm going to show the work to do that below:
2x - y = 4
-2x -2x (Here I am subtracting 2x)
- y = 4 - 2x
(-1)(- y) = (-1)(4 - 2x) (Now I'm multiplying both sides by -1 to make y positive)
y = 2x - 4 (And just for neat purposes I'm going to put the 2x in front of the 4)
Now you have your equation ( y=2x-4 ) and you're ready to put it on the points of your graph.
Start on the point (0, -4) to represent the y axis.
y = 2x - 4
Then, your rise (2) over your run (1)
so your coordinates for a line will be:
(0, -4) (-2, 1) (1, 0)
You only need to plot these three to connect your line.
I appologize for my lack of visuals i understand this might be confusing, however if you have any further questions feel free to let me know!
Answer:
25
Step-by-step explanation:
I believe
-3^2 + -4^2
9+16=25
6x + 1 - 5x = 7 when x = 2
To check this answer, you simply need to plug in 2 for x in the original equation.
6x + 1 - 5x = 7
6(2) + 1 - 5(2) = 7
Simplify.
12 + 1 - 10 = 7
Simplify.
13 - 10 = 7
Simplify.
3 = 7
3 ≠ 7 Therefore x does NOT equal 2.
