c: $ 1
d: $ 61
Answer:
Answer is C!
Step-by-step explanation:
The -2 is the y intercept and 1/3 is the slope.
The slope determines the angle of the line and the Y intercept determines how high or low that line is placed. To graph it I like to use a method called rise over run. First I identify the Y intercept then I identify the slope. From there I start at the Y intercept and Find the line. Definitely look up some tutorials on rise over run to plot equations!
2x + 2y = 4
what is the solution of the system of equations?
Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
Answer:
{3,-1}
