Please help! Write the slope-intercept form of the equation for the line.

Mathematics

Answer:

C

Step-by-step explanation:

The slope intercept of a line is y=mx +b where

  • m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
  • b is the y-intercept for value on the y-axis for which the line crosses it.

This graph crosses the y-axis (the vertical line) halfway between -1 and -2. This  is -3/2. This means only answers a, c, and d are options.

The graph moves up from -3/2 to its next point at (-4,0). We calculate the slope using:

Slope:m=\frac{y_2-y_1}{x_2-x_1}

We substitute x_1=0\\y_1=-1.5 and x_2=-4\\y_2=2

m=\frac{2-(-1.5)}{-4-0}

m=\frac{2+1.5}{-4}=\frac{3.5}{-4} =-0.875

This decimal is equivalent to -7/8. This means C is the answer.

How many solutions does the equation 6y - 3y -7 = -2 +3 have?
kenny6666 [7]

Answer:

6y - 3y - 7 = -2 +3

Simplify both sides:

3y -7 = 1

Add 7 to both sides:

3y = 8

Divide both sides by 3:

y = 8/3 = 2 2/3

There is only one solution.

I’m stuck on this problem
slavikrds [6]

The value of the f(-8) from the given f(x) is 1/53.

According  to the statement

we have given that the value of f(x) and with the value of this we hav eto find the value of f(-8).

So, For this purpose,

The given value of f(x) :

The function f(x) is

f(x) = 1 / x^2 -11

Now we find the value of the f(-8) then

For this put Put x is -8 in the f(x) then the equation become

f(x) = 1 / x^2 -11

f(-8) = 1 / (-8)^2 -11

f(-8) = 1 / 64 -11

f(-8) = 1 / 53.

here the value becomes 1/53.

So, The value of the f(-8) from the given f(x) is 1/53.

Daniel had a 22-foot-long rope that he cut into eight equal pieces. Which equation can be used to determine the length, r, of ea
ivann1987 [24]

Answer:

Option C.

Step-by-step explanation:

Let

r-----> the length of each piece

we know that

To find the length of each piece, divide the total length of the rope (22 ft) by the number of pieces (8 pieces)

so

8r=22 -----> equation that represent the situation

r=\frac{22}{8}\ feet -----> the length of each piece
