Question

Can someone please help me? I really need help
Find the point-slope form of the equation that goes through these two points.
(1, 20) and (8, 4.5)

Answer 1

The formula is y-(y coordinate)=m(x-(x coordinate))

You need to find slope first:
Points: (1,20)(8,4.5)

From these points you need to plug them into the slope formula which is your 2nd y coordinate minus the 1st y cooridinate all over the 2nd x coordinate minus the 1st coordinate.
(4.5-20)/(8-1) this comes out to -5.5 over 7.

Now you just plug the slope and one of the coordinate pairs into the formula.
Once you're done you get y-20=-55 over 7(x-1).

Thank you soo much!!
