we have

y=3x-1

we know that

If the point is an equation solution, it must satisfy the equation.

<u>case a</u>) (4,1)

Substitute the values of x and y in the equation

1=3*4-1

1=12-1

1\neq11 -------> the point is not solution of the equation

<u>case b</u>) (2,5)

Substitute the values of x and y in the equation

5=3*2-1

5=6-1

5=5 -------> the point is solution of the equation

<u>case c</u>) (4,3)

Substitute the values of x and y in the equation

3=3*4-1

3=12-1

3\neq11 -------> the point is not solution of the equation

<u>case d</u>) (0,-3)

Substitute the values of x and y in the equation

-3=3*0-1

-3\neq-1 -------> the point is not solution of the equation

therefore

<u>the answer is</u>

The point (2,5) is solution of the equation

I don't know where you got those answers, but the actual equation that represents those points is: y = -1/2x + 11. None of those listed above are correct.

Please Help Me With This Math Problem

Answer:

Yes the relationship is linear and given by:

y+2=-\frac{5}{4} \,(x+9) (first option of your list)

Step-by-step explanation:

Yes, it is a linear expression. As we did in previous exercises, we calculate the difference between consecutive y values of the table, and write down the answers we get:

-7-(-2) = -7+2 = -5

-12-(-7) = -12 +7 = -5

-17 - (-12) = -17 + 12 = -5

We notice that all of them give "-5"

Now we evaluate the difference between consecutive x-values in a similar fashion:

-5 -(-9) = -5+9 = 4

-1-(-5) = -1+5 = 4

3-(-1) = 3+1 = 4

We see that they all give 4 as the difference.

That means that the rate of change \frac{y_2-y_1}{x_2-x_1} =\frac{y_3-y_2}{x_3-x_2}=\frac{y_4-y_3}{x_4-x_3}=\frac{-5}{4}

This means that the slope (rate of change) of the line is "-5/4"

We can now use the general point-slope form to write the equation of the line, using the first pair of the table as our selected point, and using "-5/4" for the slope:

y-y_0=m\,(x-x_0)\\y-(-2)=-\frac{5}{4} \,(x-(-9))\\y+2=-\frac{5}{4} \,(x+9)

which is the first expression listed among your possible answer choices.

What is the slope of the line?​
VladimirAG [237]

Answer:

-1

Step-by-step explanation:

Pick two points on the line

(0,1) and ( 2,-1)

Using the slope formula

m = (y2-y1)/(x2-x1)

    = ( -1 -1)/(2-0)

     = -2/2

    = -1
