The slope of the line that passes through the points (-10,y) and (5, 2) is 2/5. What is the value of y?
1 answer:
Answer:
C, -4
Step-by-step explanation:
slope=change in y/change in x


multiply both sides by 2/5

simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4


bring y to the other side by adding y on both sides

subtract 6 on both sides

so y is -4
