Find the equation of the line. Use exact numbers

dsp73

Answer:

y= 3x + 3

Step-by-step explanation:

From the graph we get 2 points: (-1,0) and (0,3)

(0,3) tells us that b = 3

and we use the equation $\frac{y1-y2}{x1-x2}$ to calculate m

m = $\frac{3-0}{0- (-1)}$ = 3/1 = 3

so plugging m and b into y = mx + b gives us

y = 3x + 3

what is the surface area of a rectangular prisim with a base length of 9 yd, base width of 7 yd,and a height of 4 yd?

krek1111 [17]

Answer:

254 yds²

Step-by-step explanation:

There are 6 faces of the prism we need to calculate the area of for a rectangular prism.

The base and top of the prism measure 9x7 yards each, so there are two faces with an area of 63 yds² (9 x 7 = 63)

The sides of the prism measure 4x7 yards each, so there are two faces with an area of 28 yds² (4 x 7 = 28)

The front and back face of the prism measure 9x4 yards each, so there are two faces with an area of 36 yds² (9 x 4 = 36)

The total surface area is

2(63) + 2(28) + 2(36) = 254 yds²

What is the slope of the line shown below?

Sergio039 [100]

Answer:

Option D

Step-by-step explanation:

We are given the two points of (5, 11) and (-5, -1).

Use the slope formula.

$m=\frac{rise}{run}=\frac{-1-11}{-5-5} =\frac{-12}{-10} =\boxed{\frac{6}{5}}$

The correct option should be Option D.

Hope this helps you.
