Slope Intercept
The general form of a linear equation in slope intercept form.
y = mx +b
What is the general form for point-slope form?
y -y1 = m( x - x1)
What is the general form for Standard form
Ax+By=C
How do you find the x intercept of an equation?
Plug in 0 for y
What kind of line will this inequality have: y>2x+3
Dashed
In the equation y= 3x +5 what is the slope and the y intercept?
m= 3 and b= 5
y - 3 = 2(x+4) what is the slope and the point
m= 2, (-4, 3)
What are the two methods to solve Standard Form
1. Plug in 0 for x and y
2. Solve for y
How do you find the y intercept of an equation
Plug in 0 for x
or put into slope- intercept form
Where will the shading be for this inequality: y<x-1
Below
In the equation y = -2x + 4, what does the negative sign tell me about which way the line will point?
Downward
What is the equation for a line with a slope of -5 that passes through (3, 4)
y - 4= -5 (x-3)
What is the slope for 3x + 2y = 8
-3/2

-2
Where would you shade for x>4
Right
How would you graph y = 1/2 x -3
First plot the y-int at -3, then rise 1 and run over 2.
What is the equation of a line with slope 3, and point (1, -2)
y +2 = 3 (x-1)

(3,0) and (0,6)
How do I know when to flip the sign when solving an inequality?
multiplying or dividing by a negative
