Just took the test hope this helps :D
Answer:

Step-by-step explanation:
Point-slope form is represented by
. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.
To find the slope, use the slope formula
.
and
represent the x and y values of one point the line crosses, and
and
represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:

Thus, the slope is
.
2) Now, using the point-slope form of
, substitute
,
, and
for real values in order to write an equation in point-slope form. The
represents the slope, so substitute
in its place. The
and
represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for
and
. (I chose (8,9)). This gives the following equation and answer:

Answer:
A right triangle
Step-by-step explanation:
It's where the altitudes all intersect. In a right triangle, the legs of the right triangle are the altitudes-- especially evident when the right angle is at the base. The altitude from the hypotenuse to the right angle also passes through the right angle.
