I need help with this ASAP plz Can you explain so I can understand it better?

Answer

Step-by-step explanation:

For exercises one- three, your slopes are m=, so thinking of the slope intercept form y=mx+b. Plug in the (x,y) coordinates into the equation

for example question 1:

1=4(3)+b

or for question 2:

7=-3(2)+b

For exercises 4 and 5, simply just find the y intercept by seeing where on the why axis the line is one a certain point. and to find the slope do the equation

y2-y1/x2-x1

for example number 4:

-1-2/4-2 and your slope would equal - 3/2

so your equation would be

y= -3/2+5

hope this helps ;)

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
