MATH 1201 - College Algebra - CHALLENGE 1: Graphing and Writing Linear Equations and Inequalities 
To find the corresponding y-value when the x-value is 3, find 3 on the horizontal axis, and go up until you find the coordinate point. This matches with 7 on the 
vertical axis. To find the corresponding x-value when the y-value is 9, find 9 on the vertical axis, and go over until you find the coordinate point. This matches with 
17 on the horizontal axis.

Identify the slope of a line perpendicular to a given line. 
What is the slope of a line perpendicular to the line ? 
A.) 
B.) 
C.) 
D.) 
D.)Correct. 
Recall that perpendicular lines have opposite (one positive, one negative) reciprocal (flipped fraction) 
slopes. If the slope of this line is , then to find the slope of a line perpendicular, flip the fraction from 
to AND change from a positive to...

The form is called slope-intercept form. To identify the equation of this 
graph in slope-intercept form, we need to identify two parts to the line: its slope, noted 
by the variable ; and its y-intercept, noted by the variable . Let's start by finding the 
y-intercept. 
We can easily identify the y-intercept by examining when the line crosses the y-axis. 
This occurs at so this means that is the variable in the equation. 
Now that we have the y-intercept, we ca...
