Question

find the value of m or b if the given line passes through the given point
y=5/4x+b ; (4,8)
y=4x+b ; (3/2,11/2)
y=-2x+b ; (1,-2)

Answer 1

The three sets of equations have m it is the number in front of x .... to find b in all three plug in the x and y coordinate with the corresponding point.

EX: First one: X = 4, Y = 8
