Example Questions
Example Question #1 : Slope & Intercept
What is the slope and y-intercept of this line: ?
Step 1: Move the y-term to the other side. We will add 4y.
Step 2: Move the constant to the other side. We will subtract 12.
Step 3: Divide by the coefficient in front of the y term. In this question, we divide all terms by 4.
Step 4: Identify the slope and the y-intercept. The slope is the number that is in front of the x term, and the y-intercept is the number that comes after the x-term.
In this question, the slope is and the y-intercept is
.
Example Question #1 : Slope & Intercept
Find the slope of a line that passes through points and
.
Slope is undefined.
The formula for slope is:
When the y coordinates are the same, as in this case both were -1, this would form a horizontal line. The slope of a horizontal line is zero.
Example Question #1 : Slope & Intercept
Find the slope of a line that passes through points and
Slope is undefined.
Slope is undefined.
The formula for slope is:
Slope is undefined.
If the x coordinates are the same, as in this problem both x coordinates are 4, then this will be a vertical line. The slope of a vertical line is undefined.
Example Question #2 : Slope & Intercept
Find the slope of a line that passes through points and
Slope is undefined.
The formula for slope is:

Example Question #31 : Coordinate Geometry
The points given lie on a line. Find the slope.
slope =
rise = changes in y
run = changes in x
The change in the coordinates is that the numbers are decreasing by 3 or -3.
The change in the coordinates is that the numbers are increasing by 2 or +2;
slope =

Example Question #1 : Slope & Intercept
The points given lie on a line. Find the slope.
Slope is undefined.
slope =
rise = changes in y
run = changes in x
There is zero change in the coordinates.
The change in the coordinates is that the numbers are increasing by 2 or +2.
slope =
If the coordinates are the same, then it will be a horizontal line. The slope of a horizontal line is 0.
