What does the graph of a linear function look like?
A straight line.

What are the x and y-intercepts of the following graph?
x-intercept: 2.5
y-intercept: -2
25
Write the equation of a line that passes through (0, 3) with a slope of -4
y = -4 x + 3
25
Identify the slope of the linear equation
y = -x + 6
The slope is -1/1. Down one, right 1.

True or False:
A higher "m" value will make the graph steeper.
True!
"m" is the slope of the line. Higher numbers mean you will rise farther, making your line more steep.

When graphing in Slope - Intercept form, y = mx + b, the y stands for the y-intercept
False
b stands for the y-intercept

What is the formula used to find Slope?
the steepness of a line
50
True or False: When graphing lines in Standard Form (Ax + By = C), you must know the slope and a point.
False. You must use the x and y intercepts.

Where is the x-intercept located?
The point where a graph crosses the x-axis.
75
TRUE or FALSE

m = slope
b = y-intercept

When calculating slope, you should always label your points (x1, y2) and
(x2, y1)
FALSE
Label them (x1, y1) and (x2, y2)
