Slope is -2/5 and y-intercept is 2

Step-by-step explanation:

• Step 1: Write the equation in slope-intercept form y = mx + b

2x + 5y = 10

5y = -2x + 10

y = -2/5 x + 10/5

y = -2/5 x + 2

• Step 2: Find the slope and y-intercept from the equation.

Slope, m = -2/5

y-intercept, b = 2

Answer:

1/3

Step-by-step explanation:

21.

Probability of an even happening is equal to the number of desired outcomes divided by the total number of outcomes.

The desired outcomes here are 3 and 9. There are two desired outcomes.

The total number of outcomes is 6.

p(event) = (number of desired outcomes)/(total number of outcomes)

p(3 or 9) = 2/6 = 1/3

Answer:

y = -4x -21

Step-by-step explanation:

Use slope intercept form:  

y = mx + b

use slope from original line:  y = -4x - 1 so slope is -4

use the given point (-4,-5) for the x and y values and solve for b

-5 = -4(-4) + b

-5 = 16 + b

-5 - 16 = b

-21 = b

substitute b value in slope intercept form

y = -4x - 21

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

So far we know the slope and can plug that into the equation like so...

y = -3x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(4, -2)

-2 = -3(4) + b

-2 = -12 + b

10 = b

y = -3x + 10

Hope this helped!
