Answer:

Step-by-step explanation:

To find the slope it is: change in y/change in x

y_1 - y_2/x_1 - x_2. It can also be the variable sub 2, minus sub 1.

For this it is:

-2-4/4-6

-6/-2

m = 3

Slope intercept form is y = mx+b. Now we can sub in m. y = 3x+b.

To find b, sub in numbers from one of the points for x and y. I'm going to use (4,-2). Since in this case, -2 = y, and 4 = x, then those are the numbers I'm going to replace x and y with.

-2 = 3(4) +b

-2 = 12+b

-14=b

If -14 = b, and 3 = m, then your equation is y = 3x-14

kipiarov [429]

Step-by-step explanation:

B. 8

she will run for 8 miles,

find Amy's speed

convert the minutes into hours by dividing by 60

$\frac{2}{15 \times \frac{1}{60} } \\ = 8 \: miles \: per \: hour$

find the number of miles ran by multiplying the speed by the time, ie

$8 \times 1 = 8 \\ \: therefore \: the \: answer \: is \: \: 8 \: miles$

Round 36 to the nearest hundredth. for the brainiest

mestny [16]

36 to the nearest hundredth is just 36

To round 36 to the nearest hundredth consider the thousandths' value of 36, which is 0 and less than 5. Therefore, the hundredths' value of 36 remains 36
