Answer:

Well, the first thing you must do is find the slope

(0,2) (1,-3) I am going to make x1= 0, y1=2, x2=1 and y2= -3

Now, I am going to use the formula for the slope, which is

y2-y1/(x2-x1)

[-3-2]/(1-0)= -5/1 or just -1

Next, I am going to use the point slope form, which is

y-y1=m(x-x1). m=5, x1=0, y1=2

y-2= -5(x-0)

y-2=-5x

+2 +2

y= -5x+2 This is the slope intercept form.

we are done. I am glad to see that you are doing math on a Saturday night.. Good luck... Please rate my answer:)

Irina18 [472]

Answer:

1.2 + 3x6 = 19.2

2.4(8-3) = 11.25

3.7 + 8 (3 + 2) = 43.7

4(6 - 5) + (8 x 10) = 84

Hope this helps!

Have a great day

F(x)=5^x if F(-2) what does this equal
KengaRu [80]

Answer:

\frac{1}{25}

Step-by-step explanation:

Using the rule of exponents

a^{-m} = \frac{1}{a^{m} }, hence

f(- 2) = 5^{-2} = \frac{1}{5^{2} } = \frac{1}{25}
