Answer:
Hi There the correct answer is {x,y} = {-1,-10}
System of Linear Equations entered :
[1] 3x - y = 7
[2] 4x - 2y = 16
Graphic Representation of the Equations :
y + 3x = 7 -2y + 4x = 16
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 3x - 7
// Plug this in for variable y in equation [2]
[2] 4x - 2•(3x-7) = 16
[2] -2x = 2
// Solve equation [2] for the variable x
[2] 2x = - 2
[2] x = - 1
// By now we know this much :
x = -1
y = 3x-7
// Use the x value to solve for y
y = 3(-1)-7 = -10
Solution :
{x,y} = {-1,-10}
Hope it helps!
Answer:
the slope is 
Step-by-step explanation:
Notice that you are given two points to use for the slope calculation:

So we use the formula for the slope of a line given two points:

1 is the correct answer my guy
The domain is the complete set of values for which x, or the independent variable, is possible for.
The range is the complete set of values for which y or the dependent variable is possible for.
Hope this helps.
