Math Problem Statement
When a student sets y=0 into a linear equation, she can solve for x and gets x=-3. When she sets x=0 and solves the equation, she gets y=4. Which of the following is the correct statement of the intercepts and graph?
x-intercept: (-3,0)
y-intercept: (0,4)
x-intercept: (-3,0)
y-intercept: (0,4)
x-intercept: (0,-3)
y-intercept: (4,0)
x-intercept: (-3,0)
y-intercept: (4,0)
Solution
The correct statement of the intercepts is:
- x-intercept:
- y-intercept:
This matches the first option in the list:
- x-intercept:
- y-intercept:
This means that when , the point on the x-axis is , and when , the point on the y-axis is .
