Find the slope of the line through (-9,-10) and (-2,-5)
A.- 5/7****
B.-7/5
C.5/7
D.7/5
Slope = (y2 - y1)/(x2 - x1)
= (-10 + 5)/(-9 + 2)
= (-5)/(-7)
= 5/7
The correct answer is C.
Always try to recheck your work. If you imagine the given points on the cartesian plane, you will see that they are on a line moving upwards, which must therefore have a positive, not negative, slope.
