Answer:

  2x +3y = -4

Step-by-step explanation:

The slope of the line is given by the slope formula:

  m = (y2 -y1)/(x2 -x1

  m = (-4 -4)/(4 -(-8)) = -8/12 = -2/3

This can be used in the point-slope formula to find an equation of the line:

  y -y1 = m(x -x1)

  y -4 = -2/3(x -(-8)) . . . . substituting for (x1, y1) and m

Multiplying by 3 eliminated fractions:

  3(y -4) = -2(x +8)

  3y -12 = -2x -16

Adding 2x+12 to both sides gives the standard form equation:

  2x +3y = -4

Which slope is shallower a slope of 3.5 or a slope of 4.6.
suter [353]

Answer:

-> a slope of 3.5

Step-by-step explanation:

The smaller the slope the smaller the incline, here 3.5 > 4.6 so the 3.5 slope is shallower.

Find the value of x and y. SHOW YOUR WORK
Leona [35]

Answer:

x=21, y= 35

Step-by-step explanation:

3x+7=5x-35

(subtract seven from -35)

3x=5x-42

(subtract 5 from 3)

-2x=-42

(-42/-2= positive number)

x=21

y+75=3y+5

(subtract 75 from 5)

y=3y-70

(subtract 3y from y)

-2y=-70

y=35

An x-method chart shows the product a c at the top of x and b at the bottom of x. Above the chart is the expression a x squared
Bond [772]

Answer:

The other factor is (x + 2).

Step-by-step explanation:

If x - 10 is a  factor of x^2 - 8x - 20 then we must find another factor that includes +2x, so that we have -10x + 2x = -8x.  That factor is (x + 2):

x^2 - 8x - 20 = (x - 10)(x + 2)

As a test, multiply -10 and +2.  We get -20, matching the constant of the given polynomial.  Also, -10x + 2x = -8x, another match.
