The data is linear as the x and y are both increasing at a set amount.
X increases by 2 each time Y increases by 4.
Our slope would be 2x because every time x goes up 1 y goes up 2.
With that knowledge I can figure that if you increased the point -1,17 by the slope to get 0,21 that would be the y intercept.
Thus the equation should be y=2x+21
Answer:
Quadrent 2
Step-by-step explanation:
You need to fill in the blank spaces in the chart.
For the first row, read the word form and try to put it into numbers. It would be 5,370.
Then, you need to put it into expanded form. This is a bit harder since you need to separate all of the numbers. It would be 5,000+300+70+2.
For the second row, you have to work backwards. This time it’s 50,370. Write it in standard form and word form as I taught you. Good luck!

System of Linear Equations entered :
[1] -4x - 3y = -7
[2] 16x - 3y = 13
Graphic Representation of the Equations :
-3y - 4x = -7 -3y + 16x = 13
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 16x = 3y + 13
[2] x = 3y/16 + 13/16
// Plug this in for variable x in equation [1]
[1] -4•(3y/16+13/16) - 3y = -7
[1] - 15y/4 = -15/4
[1] - 15y = -15
// Solve equation [1] for the variable y
[1] 15y = 15
[1] y = 1
// By now we know this much :
x = 3y/16+13/16
y = 1
// Use the y value to solve for x
x = (3/16)(1)+13/16 = 1
Solution :
{x,y} = {1,1}
