Can anyone tell me how to graph 7x+y=5
Answers
Answer 1
Answer:
You have the equation 7x+y=5
But you must rearrange this into y=mx+b form
to do this subtract 7x from both sides
y= -7x+5
On the y axis plot a dot on 5 because that is the y intercept.
To find the x intercept let y=0
0= -7x+5
1. Subtract 5 to both sides
-5=-7x
2. Divide by -7 to both sides
x= -5/-7
x=5/7
The x intercept is 5/7, so on the x axis mark a dot on 5/7 which is approximately at 0.7
Once you have marked one dot on the y axis at 5 and another dot on the x-axis at 0.7 then you draw a straight line through these points and you have graphed the function 7x+y=5

Answer 2
Answer:
To graph an equation, you first need to solve it for y. This means turning the equation into this form: Y=.......
For your equation, once you solve it for Y, you get this:
Now, the coefficient of X is a very crucial part of graphing an equation. Once the equation is solved for Y, the coefficient of X is going to be the slope of the line you are graphing. The slope of a line is how much Y goes up every time X is increased by 1.
To graph an equation, you need to put in a number for X and find the matching value for Y and then graph that point. To do this, you will need a coordinate plane. I can't show you what that looks like on here. But, I will do my best to explain how it is done.
Now, for your equation:
Simply chose a number for X and find the matching value for Y. I'll try 0 for an example:
%20%2B5)
-7 * 0 is 0. Therefore, your new equation looks like this:
Therefore, one "Solution pair" to this equation is (X=0,Y=5)
Simply repeat this process and plot the solution pairs on the coordinate plane and then connect the dots.

I have to solve by elimination.
Will someone help me please?
Answers
To do elimination, you combine the two equations by adding
-9x + y = 16
+ x - y = 0
-8x + 0y = 16
Now that there are 0y, we can solve for x:
-8x = 16
divide both sides by -8
x = -2
To solve for y, plug the answer you got for x in to the original equations.
-9x + y = 16
-9(-2) + y = 16
18 + y = 16
y = -2
x - y = 0
-2 - y = 0
y = -2
x = -2 and y = -2
-9x + y = 16
+ x - y = 0
-8x + 0y = 16
Now that there are 0y, we can solve for x:
-8x = 16
divide both sides by -8
x = -2
To solve for y, plug the answer you got for x in to the original equations.
-9x + y = 16
-9(-2) + y = 16
18 + y = 16
y = -2
x - y = 0
-2 - y = 0
y = -2
x = -2 and y = -2
-9x+y=16
x-y=0
add the two equations, the y's cancel each other out
-8x=16
divide by -8
x=-2
x-y=0
add the two equations, the y's cancel each other out
-8x=16
divide by -8
x=-2

Since we don’t see an end on the X value we know that every number could be X. This mean X is an element of reels, so the domain answer is XER, the y however is over -2, so y>-2 but it can be any number above that so it is also an element of reels. So y>-2,YER would be the range
