Question

Right triangle ABC is shown on the graph below. If the point (-4, y) lies on the line that goes through side BC of the triangle, then what should be the value of y?

the answers given were

A. 0
B. -5
C. 1
D. -1

Answer 1

C. 1

Explanation:

Answer 2

C. 1

Explanation:

The line containing segment BC has a slope of 1 and a y-intercept of 5 (at point B). Thus, its equation is ...

y = x + 5

For the value of x = -4, the value of y is ...

y = -4 +5 = 1

Point (-4, 1) is on the line containing segment BC.
