Question

2. A line goes through the points (4, 8) and (-4, 6).

(a) What is the slope of the line? Show your work
(b) Write the equation of the line in point-slope form. Show your work
(c) Write the equation of the line in slope-intercept form. Show your work.


Any body can help?

Answer 1

(a)
`(6-8)/(-4-4)=(-2)/(-8)=\boxed{1/4}`

(b) Using the point (4,8), we get
`\boxed{y-8=(1)/(4)(x-4)}`

(c) Rearranging into slope-intercept form,

`y-8=(1)/(4)(x-4)\\\\y-8=(1)/(4)x-1\\\\\boxed{y=(1)/(4)x+7}`
