Question

Find the slope, if it exists, of the line containg the pairs of pointsplease answer them all :(1. ( -4, -1 ) and ( 4, 4 )2. ( 0, 3 ) and ( 4, 0 )3. ( 0, 1 ) and ( 3, 0 )4. ( 7, 8 ) and ( -7, 8 )5. ( 1, 5 ) and ( -8, 5 )

Answer 1

The formula for determine the slope is given by

m = ( y2-y1)/(x2-x1) where ( x1,y1) and (x2,y2) are points on the line

m = ( 4 - -1)/(4 - -4)

Rewriting

m = ( 4+1)/( 4+4)

= 5/8

The slope is 5/8
