Find the slope when given these two points...
(1, 0) and (5,4)
slope = 4/4 or 1
Solve by substitution and write your answer as an ordered pair (x, y)
x = 2
2x - 5y = 19
( 2, -3)
Find the y intercept
4y = 4x - 20
y = -5
(0, -5)
3(2x - 10)
6x - 30
When is our final exam?
Thursday
Write in point slope form....
m = 2 and (2, -5)
y + 5 = 2(x - 2)
Solve by elimination
2x + 5y = 27
-2x + 4y = 18
( 1 , 5)
Find the x intercept
3y = 15x - 30
x = 2
(2,0)
3(x - 6) = 5(x + 4)
x = -19
Write an equation perpendicular to the given line passing through point (2, 5): y = -1/3x - 3
y = 3x -1
Write in slope intercept form
m = 3 and (6, 1)
y = 3x - 17
Will the graph of this inequality have a solid or dotted line?
Will it shade up or down?
y > 3x - 2
Dotted and shade up
Find the x and y intercept
7x - 2y = 28
x = 4
(4,0)
y = -14
(0,-14)
(x - 2)(x + 7) (use FOIL)
x^2 + 5x - 14
