Determine the value of "r" so the line that passes through each pair of points has the given slope
(6,3)(r,2) slope= 1/2
:
Use the slope formula: = m
;
Assign the given values as follows:
x1=6; y1=3
x2=r; y2=2
m = 1/2
:
= = =
Cross multiply:
r - 6 = 2(-1)
r = -2 + 6
r = +4
;
;
Check solution; x2=4:
=
=
