What is the shape of the graph of a linear function?
Linear functions are those whose graph is a straight line.

What are the x and y-intercepts of the following graph?
x-intercept: 2.5
y-intercept: -2
100
Write the equation of a line that passes through (0, 3) with a slope of -4
y = -4 x + 3
100
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.

TRUE or FALSE
A line with a slope that is undefined has a y-intercept
FALSE...it does not go through the y-axis

Find the slope of a line that passes through the points (0, 5) and (2, 10)
m = 5/2
200
True or False:

In Slope Intercept Form, what letter represents slope and what letter represents the y-intercept?
m = slope
b = y-intercept

What is one other word that means the same thing as the x-intercept?
Any one of these:
Roots, zeros, solutions

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

True or False;
When graphing this equation: y= -2x +3 , start by placing a point on the y-axis at -2.
False. Begin at the y-intercept, which is +3.

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