Question

Write the slope-intercept form of the equation for the line.



A. y = -5/8x + 1/2

B. y = 8/5x - 1/2

C. y = 5/8x + 1/2

D. y = 8/5x + 1/2

Answer 1

to find the slope of the line

slope formula

y1 - y
m = ----
x1 - x

slope of the line

y1- y = m ( x1 - x)

plug in the values you got for slope
y1 - y
m = ----
x1 - x

( y, x ) , (y1 , x1 )
and use the value you got for slope
to solve to get the equation for the "slope of the line"

slope intercept formula
is just a rearrangement

y= mx + b

y = y value
x = x value
m = slope
b = y intercept
