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

Need help with these two
Brilliant_brown [7]
Before we start to answer, let's get our formulas put in.
4 qt = 1 gal.
1 c = 0.5pt (or 2 cups to 1 pt)

Now that we've gotten the formulas out of the way, let's plug in our numbers.

We have 5 qt.
Since we have 4 qt per gal, let's subtract 4 from 5.
5 - 4 = 1. We have 1 gal (due to having a whole 4) and 1 qt left over.
5 qt = 1 gal 1 qt.

We have 7 c.
Since we have 2 cups per pint, let's divide 7 by 2.
7 / 2 = 3.5

We have 3.5 Pt.

7c = 3.5pt

Your answers are:
1 gal 1 qt
3.5pt

I hope this helps!

Answer:

1/4
