Find the equation of the line.<br> Use exact numbers.
True [87]

Answer: y=2x+4

Step-by-step explanation:

From the graph, we already know what the y-intercept is. The line crosses the y-axis at (0,4). Therefore, 4 is our y-intercept.

For the slope, we can take any 2 points on the graph and then use the formula m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } to find slope. Let's use (1,6) and (2,8).

m=\frac{8-6}{2-1}=\frac{2}{1}  =2

Now that we know the slope, we can fill in our slope-intercept equation.

y=2x+4

The area of a rectangle is 2x^2 + 7x + 6. If the width is x + 2, what is its length?
Blababa [14]

Answer:

Area of a rectangle = Length × width

2 {x}^{2}   + 7x + 6 = length \times (x + 2)\\  \\  length = \frac{2 {x}^{2} + 7x + 6 }{x + 2}   \\   \\  \\  =  \frac{(x + 2)(2x + 3)}{x + 2}  \\  \\  = 2x + 3

So ; Length = 2x + 3

I hope I helped you^_^
