Question

The line y = mx + 7 passes through the point ( -2, 5). find m.

the line y = 2x + c passes through the point ( 1 , 4). find c

Answer 1

Question 1

y = mx+7

5 = m*(-2)+7

5 = -2m+7

-2m+7 = 5

-2m = 5-7

-2m = -2

m = -2/(-2)

m = 1 is the final answer

===============================================

Question 2

y = 2x+c

4 = 2(1)+c

4 = 2+c

4-2 = c

2 = c

c = 2 is the final answer
