Question

I'd appreciate your guys' help! :)

A line goes through the point (9,8) and (4,-12).

Write the equation of the line in point-slope form. Please show your work.

Write the equation of the line in slope-intercept form. Please show your work.

Answer 1

Point slope form is :

8+12 = m(9-4)

8+12= 9m -4m

20= 5m

20/5= 5m/5

m= 4

Slope form

8= 4(9) +b

8= 36+b

-28=b

Y= 4x -28
