Since the formula is $\frac{1}{2}h(B1+B2)$ , here's the answer.

First we do $\frac{1}{2}10$ , which gives us 5.

Then we do $5(20+8)$ , which gives us $5(28)$ .

At last we do $5*28$ , and we get 140.

So, the answer would be 140.

Hope this helped! c:

Answer:

Slope = 2

Y-Intercept = 4

Equation of Line is y=2x+4

Step-by-step explanation:

y-intercept is the point in the y-axis, where the line cuts it. So, looking at the graph, the y-intercept would be y = 4

To figure out the slope, we take any two points and calculate using the formula:

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

Where, m is the slope

$(x_1,y_1)$ is the first coordinate, and

$(x_2,y_2)$ is the second coordinate

<em>Let's take two points as: (-2,0) & (-1,2)</em>

<em />

Plugging these into the formula we get the slope as:

$m=\frac{y_2 - y_1}{x_2 - x_1}\\m=\frac{2-0}{-1--2}=\frac{2}{1}=2$

Hence slope is 2

Equation of the line is given as y = mx + b, where m is the slope (in our case 2) and b is the y-intercept (in our case 4). Thus:

Equation of Line: $y=2x+4$
