Answer:

B: 3x + y = − 7

Step-by-step explanation:

As we move from (-5, 8) to (-3, 2), x increases by 2 and y decreases by 6. Thus, the slope of the line thru these two points is m = rise / run = -6/2 = -3.

Applying the point-slope form of the equation of a straight line,

y-k = m(x-h), we obtain y - 2 = -3(x + 3).

Alternatively, y = -3x - 9 + 2, or

y = -3x - 7

and this can be rewritten in the form 3x + y = -7 (Answer B)

AJLK ~ APQR. Find the value of . 22 14 7 1 8 K 16 20 2=

In-s [12.5K]

Answer:

x = 11

Step-by-step explanation:

sides are proportional so you can set up a proportional and cross-multiply:

JL is to PQ as LK is to QR

x/22 = 8/16

x/22 = 1/2

2x = 22

x = 11

Find the slope of the line through each pair of points (-10,17) , (-8,-1)

svet-max [94.6K]

Slope = (y2 - y1)/(x2 - x1) = (-1 - 17)/(-8 - (-10)) = -18/(-8 + 10) = -18/2 = -9

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the tabl

Nadusha1986 [10]

We are given 4 points.

$(\frac{1}{2},2)$

$(\frac{5}{8},\frac{5}{2})$

$(\frac{3}{4},3)$

$(\frac{7}{8},\frac{7}{2})$

Using this, we can make an equation.

$y=4x$

I got $m=4$ by using the slope formula.

$m=\frac{2.5-2}{0.625-0.5}$

$m=\frac{0.5}{0.125}$

$m=4$

So the equation we have is $y=4x$

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for $y$ , which is the number of cracker packages.

$25=4x$

$x=\frac{25}{4}$

We need to use $\frac{25}{4}$ teaspoons of peanut butter to make 25 packages of crackers.

Hope this helps.

頑張って!
