Slope-Intercept Form Writing Linear Equations Halloween Answer Key
Slope-Intercept Form Overview
The slope-intercept form of a linear equation is y = mx + b, where:
- y is the dependent variable (the variable that changes)
- x is the independent variable (the variable that stays the same)
- m is the slope of the line
- b is the y-intercept (the point where the line crosses the y-axis)
The slope of a line tells you how steep the line is. A positive slope means the line goes up from left to right, while a negative slope means the line goes down from left to right. The y-intercept tells you where the line crosses the y-axis.
Writing Linear Equations in Slope-Intercept Form
To write a linear equation in slope-intercept form, you need to know the slope and the y-intercept. You can find the slope by using the following formula:
m = (y 2– y 1) / (x 2– x 1)
where (x 1, y 1) and (x 2, y 2) are two points on the line.
Once you know the slope, you can find the y-intercept by plugging one of the points into the slope-intercept form:
y = mx + b
and solving for b.
Halloween-Themed Practice
Let’s say you’re planning a Halloween party and you want to charge guests a certain amount of money for food and drinks. You know that you’ll need to charge $5 for each guest, plus a $10 flat fee for the party.
The total cost for each guest can be represented by the following linear equation:
y = 5x + 10
where:
- y is the total cost for each guest
- x is the number of guests
- 5 is the slope of the line
- 10 is the y-intercept

Expert Answers: Slope Intercept Form Writing Linear Equations Halloween Answer Key
What is the significance of the slope in a linear equation?
The slope represents the rate of change or steepness of a line. It indicates how much the y-value changes for every unit change in the x-value.
How can I determine the y-intercept of a linear equation?
The y-intercept is the point where the line crosses the y-axis. To find the y-intercept, substitute x = 0 into the equation and solve for y.
