Graph (-3, 2)
What is 3 units left and 2 units up
Write an equation in slope - intercept form y=mx+b
slope = 3
y-int = -9
What is y = 3x - 9
Graph (2, -4)
What is 2 units right and 4 units down
Write an equation in slope intercept form
2x + 3y = 6
y = -2/3x + 2
Which lines are paralell
y = 2x + 3
y = 3x + 3
y = 2x - 4
y = 2x + 3 and y = 2x - 4
slopes are same
Which point is the y-intercept on a graph
(3,2) (-1, 5) (5, 0) (0, -4)
What is (0, -4)
-5x + 10y = 10
What is the slope?
slope = 1/2
What phrase do we say when we are counting the slope on a graph?
Rise over the Run
Rise/Run
What is the slope between (3,5) and (2, 9)
Write an equation in slope-intercept form
y-int = 2
slope = -8
y = -8x + 2
Find the slope
(-3,5) (4, 9)
slope = 4/7
What is the y-intercept of y = 10x - 9
y-int = -9
Write an equation in slope-int form y=mx+b
(0,2) (3,5)
y= x + 2
How do you get y alone when equation is ax+by=c
Graph y = 2
Graph x = 3
Where do the lines intersect
(3,2)
