Does the Equation Fit the Table, True or False
Written by Adi Ackerman, Head Teacher
"Does the Equation Fit the Table, True or False" is written for 8th Grade (Ages 13-14), and it covers Common Core 8.F.B.4. A 7th grader who is already steady on linear equations can use it too, and an older student can use it as a short review.
8th grade math worksheet: test every table column in equations like y = 3x − 2, circle True or False and fix each false equation. Answer key included. Part of our slope-intercept form linear equations collection. Aligned to Common Core standards.
How do I use this worksheet?
Teach graphing first with the integer and fraction slope sheets. Then use the matching sheets, and finish with the True or False sheets and the four form sort as a review.
What students will practice
- Students will substitute each column of a table into an equation.
- Students will decide whether the equation fits every column.
- Students will write the correct equation for each false one.

Functions · 8th Grade
Standard: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

How do I use this slope-intercept form worksheet?

What does this worksheet teach?
⌄
Test every table column in equations like y = 3x − 2, circle True or False and fix each false equation. The directions on the page read: Put every column of the table into the equation. Circle True if all of them fit or False if any one does not. For each False, write the equation that fits the table. An answer key is included.
Can I use this slope-intercept form worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 8th grade linear equations, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
How do you graph a line in slope-intercept form?
⌄
Plot the y-intercept b on the y-axis. From there, move by the rise and run of the slope m to plot more points, then draw the line. For y = 2/3x − 4, start at (0, −4), go up 2 and right 3.
How do you find m and b from a table?
⌄
Find b in the row where x = 0. Find m by dividing the change in y by the change in x. If no row has x = 0, substitute one row into y = mx + b to solve for b.
How do you check if an equation fits a table?
⌄
Substitute every column of the table into the equation, not just the first. If any column does not work, the equation is false. Three True or False sheets practice this and ask for the correct equation.
