Answer:
Given,
ABC is triangle with vertices A(-2,1), B(2,2) and C(6, -2)
Slope of BC(m_1) =
Since AD is perpendicular to BC
let slope of BC be (
).
We have for perpendicular



Now equation of line passing through point A(-2,1) is

y-1=1(x-(-2))
y-1=x+2
y=x+2+1
y=x+3 which is a required equation of the altitude of AD drawn from A to BC.
C, 60 hope this helps it helped me on my test
105 ÷ 70 = 1.5
1.5 * 30 = 45
105 + 45 = 150 total shots
