Starts With S
The y-intercept and slope of both lines
y = x + 4
y = 2x + 5
Y-intercepts = 4, 5
Slopes = 1, 2
Describe how you know which variable to eliminate after the you line up the equations
8x + 5y = 9
2x - 5y = -4
The variable that has the same coefficient and opposite sign
x = 4y
2x + 3y = 22
This method must be used to solve a system of inequalities
What is graphing
y = 3x - 2
y = -x - 2
The solution to the system of equations:
r + s = -6
r - s = -10
r = -8
s = 2
y = x - 2
3x - y = 16
Describe how you would shade y<3x+4
What is below
y = -3
x = 5
