Question

find value of y if line joining points (3,y)&(2,7) is parallel to line joining points (1,-4)&(0,6)

Answer 1

Answer:

y = -3

Step-by-step explanation:

Find value of y if line joining points (3,y)&(2,7) is parallel to line joining points (1,-4)&(0,6)

Two line would be parallel if their slopes are equal

Slope of line = (y2 - y1)/(x2 -x1)

Slope of line joing (1,-4)&(0,6)

= ( 6 -(-4))/(0 - 1)

= -10

Slope of line joing (3,y)&(2,7)

= ( 7 - y)/(2 - 3)

= y - 7

y - 7 = -10

=> y = -3

Answer 2

Step-by-step explanation:

y=-3
