p=-48/-3

<h2>p=16</h2>

8) -98=7t

t=-98/7

<h2>t=-14</h2>

9) -4.4 y =-4

y=-4/-4.4

<h2>y=1.1</h2>

Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ? y+4=2(x−3) y+4=−2(x−3)

beks73 [17]

Answer:

y-4=-2(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(-4-4)/(3-(-1))

m=-8/(3+1)

m=-8/4

m=-2

y-4=-2(x-(-1))

y-4=-2(x+1)

Line l has a slope of 98. The line through which of the following pair of points is perpendicular to l? A. (−9,−6),(3,3) B. (9,−

Valentin [98]

We can employ some logic to reduce the answers we need to test. We know that the slope perpendicular to line l has to have a negative reciprocal slope, so a slope of $-\frac{9}{8}$ . We see that in A and C, as x increases so does y. That means the slope of these equations are positive, which we don't want. Now for some algebra:

$m=\frac{y_2-y_1}{x_2-x_1} \implies\\ B. \frac{6+2}{-6-9}=\frac{8}{-15} \\ D. \frac{3+5}{-6-3}=-\frac{8}{9}$

We se that D has the correct slope so that must be the answer.
