Write an equation in slope-intercept form that describes the line through the points (-2,6) and (3, 1).
vladimir1956 [14]

Answer:

y=-x+4

Step-by-step explanation:

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

m=(1-6)/(3-(-2))

m=-5/(3+2)

m=-5/5

m=-1

y-y1=m(x-x1)

y-6=-1(x-(-2))

y-6=-(x+2)

y-6=-x-2

y=-x-2+6

y=-x+4

rosijanka [135]

Answer:

$9398.50

Step-by-step explanation:

Given

\$1 = 106.40\ ALL

Required

Equivalent of 1,000,000 ALL

We have:

\$1 = 106.40\ ALL

and

\$x = 1000000\ ALL

Cross Multiply

x * 106.40 = 1 * 1000000

106.40x = 1000000

Solve for x

x = 1000000/106.4

<em></em>x = \$9398.50<em> -- Approximated</em>

Fill in the blanks to make the equation true. (x−9)(x+2)=x^2________ −18
Andrews [41]

Answer:

x² - 7x - 18

Step-by-step explanation:

Remember to follow FOIL.

First, multiply the first. (x)(x) = x²

Next, multiply the second. (x)(2) = 2x

Then, multiply the third. (-9)(x) = -9x

Finally, multiply the last. (-9)(2) = -18

Combine like terms: x² + 2x - 9x - 18

x² - 7x - 18

x² - 7x - 18 is your answer.
