Slope of (0,45) (6,33) (15,15)
Vladimir [108]

Answer:

The slope is -2

Step-by-step explanation:

Given

(x_1,y_1) = (0,45)

(x_2,y_2) = (6,33)

(x_2,y_3) = (15,15)

Required

The slope (m)

Slope is calculated as:

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

So, we have:

m = \frac{33 -45}{6 - 0}

m = \frac{-12}{6}

m =-2

2. Write the slope-intercept form of the equation of the line described.
yanalaym [24]

Answer:

y = -x + 1

Step-by-step explanation:

We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.

When two lines are parallel, they have the same slope, so the slope is going to be -1.

New equation: y = -x + b.

Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.

-3 = -4 + b

add 4 to both sides

1 = b

This means that the equation is y = -x + 1
