Given ΔABC with A(-6, -1), B(3, 7), and C(4, -6)
Since it is an altitude and pass thru B, t
hen it is perpendicular to AC.
so slope(AC) = (-1 +6)/(-6 - 4) = -5/10 = -1/2
perpendicular lines, slope is opposite and reciprocal so slope = 2
passes through B(3, 7)
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1
equation in slope intercept form:
y = 2x + 1
Answer:
i think y=3/4x-4.2

Answer:
<h2>1/5</h2>
Step-by-step explanation:
The sample space for pens is
5 red pens, 6 blue pens, 3 black pens,(5+6+3)= 14pens
The sample space for paper is
4 silver paper clips and 16 white (4+16)=20 papers
The probability of selecting a black pen and white paper
Pr(black pen)*Pr(white paper)
=3/14*16/20
=48/280
= 14/70
= 2/10
= 1/5
