These r only pratice problems i have I need help on them for a big test
Order pairs
3x - 2y = 10
5x + 3y = 4
(2,2)
(-2,2)
(-2,-2)
(2,-2)
Order pairs
x + y = 4
y = 2x + 1
(1,3)
(-1,3)
(1,-3)
(-1,-3)
need the following equation in slope intercept form.
7x - 2y = 10
-2y = -7x + 10
y = (-7/2)x - 5
y = (7/2)x - 5
y = (-7/2)x + 5
What is the y-intercept of the line represented by the equation y = 2x - 3?
(0,2)
(0,-2)
(0,3)
(0,-3)
What kind of line is created when you graph the equation x = -5?
