Which of the point-slope equations below are correct for the line that passes through points (-2, -2) and (2, 1)?

Ne4ueva [31]

Find slope first:
m =y2-y1/x2-x1
m = 1--2/2--2
m = 3/4

Select a point, insert your slope, & put it into point slope form:
y-y1 =m(x-x1)

Your final answers are:

y-1=3/4(x-2)
OR
y+2 =3/4(x+2)

AveGali [126]

Answer:

The flight took 34 minutes to arrive Bakersfield wich is 85 miles far from Santa Barbara, at a speed of $150 \ mi/hr$

Step-by-step explanation:

<u>Formula</u>

$time=\frac{distance}{speed}$

<u>Knowns</u>

$speed=150\ mi/hr$ and $distance=85\ mi$

So we can apply formula $time=\frac{85\ mi}{150\ mi/hr}=17/30 \ hr$ , then, $\frac{17hr}{30} \times \frac{60min}{1hr}=34min$ , is the time the flight took in minutes

Factor 10c^2-60cd +80d^2

ozzi

$10c^2-60cd +80d^2$

$(2c - 8d) (5c -10d)$

$this \\ is \\ because...$

$2c*5c=10c^2$

$2c * -10d=-20cd \\ -8d*5c=-40cd \\ -20cd-40cd=-60cd$

$-8d * -10d = 80d$
