The slope of the given line in the image is -4 , Option A is the answer.

<h3>What is the equation of a straight line ?</h3>

The equation of the straight line is given by

y =mx +c ,

Where m is the slope , C is the intercept

The line is passing through the point

(-1,8) ,(2,-4)

The slope is given by

m = (y₂-y₁) /(x₂-x₁)

m = (-4 - 8 )/(2 +1)

m = -12/3

m = -4

Therefore the slope of the given line in the image is -4 , Option A is the answer.

Alberto and 9 of his friends went out to eat.
1 + 9 = 10
So there are 10 people in total.
Each person paid the same amount, $18.

18 × 10 = 180

The total bill was $180.

Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.

lesantik [10]

Given:

In the given ΔXYZ,

Base = 22

Height = 23.1

Also,

Base = 31.9

Height = 15.9

To find the area of the given ΔXYZ.

Formula

The area of a triangle is

$A = \frac{1}{2} bh$

where, b be the base and

h be the height.

Now,

Taking, b = 22 and h = 23.1 we get,

$A = \frac{1}{2} (22)(23.1)$ sq unit

Again,

Taking,

b = 31.9 and h = 15.9 we get,

$A = \frac{1}{2} (31.9)(15.9)$ sq unit

Therefore,

We can find the approximate area of the triangle by following two expression

a) $\frac{1}{2} (22)(23.1)$ and

b) $\frac{1}{2} (31.9)(15.9)$
