Question 29 on the MAT0020/24C Beginning Algebra State Exam
Identify Intercepts of a Linear (ax + by = c)
29. Find the y –intercept for:
A. B. C. D.
Solution:
Find the y –intercept for:
To find the x-intercept of a linear equation make y = 0 and solve for x. To find the y-intercept of a linear equation make x = 0 and solve for y.
The first step to find the y-intercept is to substitute 0 for x and solve for y.
x |
y |
0 |
? |
x |
y |
0 |
-1 |
The second step is to write the solution as a coordinate (x, y). The value for x is 0 and the value for y is -1.
The solution is: (0, -1)
