Question 102657
1)

First find the slope through (4,3) and (-3,1)


*[invoke slope 4, 3, -3, 1]


Since the slope of the two lines are parallel, the slope of the unknown line through (1,3) is {{{m=2/7}}}. So the answer is C

2)


First find the slope through (-2,1) and (-4,-2)



*[invoke slope -2,1,-4,-2]



Now to find the perpendicular slope, simply find the negative reciprocal of {{{3/2}}}. To find the reciprocal, simply flip the fraction {{{3/2}}} to get {{{2/3}}}. Now negate {{{2/3}}} to get {{{-2/3}}}.



So the perpendicular slope is {{{-2/3}}} which means the answer is A
