Answer:
it would be 17
Step-by-step explanation:
It would be C because using the methof of rise over run, the change in x is 6 while the change in y is 17. So 14/6 woll get you 7/3.
Answer:
616 cm
Step-by-step explanation:
Answer:
Both lines are perpendicular
Step-by-step explanation:
We want to determine the relationship between the two lines.
The best thing to do is to calculate the slope of the two lines;
Mathematically;
Slope = y2-y1/x2-x1
For PQ; slope will be;
(-3-17)/(1-(-4) =-20/5 = -4
For RS
slope = (4-3)/(-5-(-9)) = 1/4
Now we have -4 and 1/4 as slopes
The product of both is 1/4 * -4 = -1
When two lines are perpendicular, the product of their slopes is -1
We can conclude that both lines are perpendicular to one another
