Calculate the slope of the line passing through the two colored points below. (1,4) (-1,-1)

leonid [27]

Answer:

Slope = $\frac{5}{2}$

Step-by-step explanation:

We can define the slope as the "change in y values" divided by the "change in x values".

By change in, we mean, 2nd point MINUS the first point values.

The points given is:

(1,4) & (-1,-1)

Change in y value:

-1 - 4 = -5

Change in x value:

-1 -1 = -2

Slope is -5/-2 = 5/2

There is no answer choice. The correct answer is 5/2

What is the Line that passes through (2,0) and (0,1)

zimovet [89]

To find the slope you use the equation:

m = (y₂-y₁) ÷ (x₂-x₁)

You plug in the two points into this equation to find m (m is the slope)

m = (1 - 0) ÷ (0 - 2)

m = 1 ÷ (-2)

m = - 1/2

Next you use this equation:

y = mx + b

Because you know m you plug it in.

y = -1/2x + b

Now you need to find b. To do so you plug in either of the points into this equation(you come out with the same answer for b)

y = -1/2x + b

1 = -1/2(0) + b

1 = b

Finally you plug in b and you get your new equation.

y = -1/2x + 1
