Algebra practice question
A line in the xy-plane has the equation y = 4 − 3x. What is the slope of the line?
Answer: -3 or −3
Rewrite as y = −3x + 4. The coefficient of x, −3, is the slope; 4 is the y-intercept.
Common wrong answers
- If you answered 3
- The slope is negative: y = −3x + 4.
- If you answered 4
- 4 is the y-intercept, not the slope.
- If you answered -4
- −4 confuses the intercept's value with the slope's sign.
