Pls work out and give detail. Use the slope formula to determine the slope of each line.

kolbaska11 [484]

Answer:

$m=0$

Step-by-step explanation:

Given

See attachment

Required

Determine the slope of the line

From the attachment, we have the following points

$(x_1,y_1) = (-4,1)$

and

$(x_2,y_2) = (3,1)$

The slope m is then calculated using:

$m = \frac{y_2- y_1}{x_2 - x_1}$

Substitute values for the x's and y's

$m = \frac{1-1}{3 - (-4)}$

$m = \frac{1-1}{3 +4}$

$m = \frac{0}{7}$

$m=0$

<em>Hence, the slope is 0</em>

Marizza181 [45]

Answer:

Step-by-step explanation:

You could factor the trinomial and solve it that way, but that is the long way. Just put a - 4 wherever you see an x.

x^2 + 3x + 2 =

(-4)^2 + 3(-4) + 2

16 - 12 + 2

The answer is 6.
