Write an equation of the line passing through each of the following pairs of points.
slavikrds [6]

Answer:

y=\frac{1}{3}+\frac{13}{3}

Step-by-step explanation:

We want to write the equation of a line that passes through (5, 6) and (-1, 4).

First, let's find our slope. We can use the slope formula:

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

Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:

m=\frac{4-6}{-1-5}

Subtract:

m=-2/-6

Reduce:

m=1/3

So, our slope is 1/3.

Now, we can use the point-slope form, which is:

y-y_1=m(x-x_1)

For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:

y-6=\frac{1}{3}(x-5)

Distribute:

y-6=\frac{1}{3}x-\frac{5}{3}

Add 6 to both sides:

y=\frac{1}{3}x-\frac{5}{3}+\frac{18}{3}

Add:

y=\frac{1}{3}+\frac{13}{3}

And we're done!

Solve for z. –z + 4= -4
slega [8]

Answer:

-z+4=-4

Step-by-step explanation:

First, you want to move the positive four to the other side to isolate the variable.

-z=-8

You cannot have a negative variable, so divide both sides by 1.

-z/1=-8/1

Your answer would be:

Z=8

Hope this helps!!
