Question

The equation of the graphed line is x+2y=5. What is the x-intercept of the graph?

A)2
B)2.5
C)5
D)5.5

Answer 1

C) 5

Picture explanation: The line intersects the x-axis at the point (5, 0). Thus, the answer is 5.

Word Explanation: We get the x-intercept when y = 0, since when y = 0, it creates the horizontal line (Which is the x-axis). Substituting y = 0, we get x+0 = 5, so x = 5
