Question

A line passes through the point (-8,1) and has a slope of -5/4.write an equation in slope-intercept format for this line

Answer 1

Point = (x,y)= (-8, 1 )

Slope = -5/4

Slope intercept form:

• y=mx+b

Where:

m= slope

b = y-intercept

So far:

y= -5/4x + b

Replace (x,y) for the given points and solve for b:

1 = -5/4 (-8) + b

1 = 10 + b

1 - 10 = b

b = -9

Final equation:

y= -5/4x - 9
