Slope & y-Intercept from y = mx + b — Easy Worksheet 1
Grade 8 · Whoobee Name: ____________________ Date: __________
Answer each question. Write a slope that is a fraction as a fraction, like 2/3.
How to solve
In y = mx + b, the slope m is the number multiplying x and the y-intercept b is the number added on its own (where the line crosses the y-axis). Keep the sign in front of each number. If there is no x term, the slope is 0; if there is no number on its own, the y-intercept is 0; and y = -x has slope -1.
Example
What is the slope of the line y = 8x + 9?
Answer: 8
Not quite. The answer is
💡 In y = mx + b, m is the slope and b is the y-intercept. Here m = 6 and b = 3. The slope is 6.
✓ Correct!
Not quite. The answer is
💡 In y = mx + b, m is the slope and b is the y-intercept. Here m = 6 and b = 3. The slope is 6.
💡 How to solve: Slope & y-Intercept from y = mx + b
In y = mx + b, the slope m is the number multiplying x and the y-intercept b is the number added on its own (where the line crosses the y-axis). Keep the sign in front of each number. If there is no x term, the slope is 0; if there is no number on its own, the y-intercept is 0; and y = -x has slope -1.
