Write the equation of the line that goes through points (9, 1) and (-1, 6) in slope-intercept form. (hint: find slope first and then use y = mx + b).

First things first, you need to find the gradient which is:

Take (9 , 1) , 9 = x₁ and 1 = y₁

Also means that in ( -1, 6 ) , -1 = x₂ and 6 = y₂

Simply plug these values into the formula:

Which simplifies to:

Which then also simplifies down to:

So the gradient is , so mx - x

Now plug this into y = mx + b with one point, such as ( 9 , 1) where 1 is y and x is 9:

1 = ( x 9) + b

Which means that this can be rearranged to make 'b' the subject, making sure the positive negative half is made positive:

1 + 4.5 = b

So the intercept is b

This would then make the y = mx + b:

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.
