Answer:
Step-by-step explanation:
The slope of straight line PR where P(2,3) and R(5,-1) are two vertices of triangle PQR will be = 
Therefore, the slope of the altitude passing through Q(-1,1) will be 
{Since, the product of slopes of two perpendicular straight line is -1}
So, equation of the altitude is 
where c is a constant.
Now, putting x = -1 and y = 1 in the above equation we get
⇒ 
Therefore, the equation of the altitude is (Answer)
Answer:
z=16
Step-by-step explanation:
z/4-2=2(take l.c.m)
or,(z-8)/4=2
or,z-8=8
z=16
Answer:
the answer i believe is right angles
Looking at the data it looks like a line. So the answer will be in y+mx+b format.
Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.
The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.
Therefore a (y=1/2x+.1) would be the correct answer
