(x,-4) and (2,8) m=-3 find the missing value

It looks like you're given a question in slope intercept form.

Which is: y = mx + b, (m = slope and b = y-intercept)

Plug M and the point you know into the equation.

y = mx + b

8 = -3(2) + b

8 = -6 + b

14 = b

Now that you have your y-intercept, add that to the equation along with m, and what you know of the missing value (the point x, -4, you have the value of y, which is -4, so you're looking for the value of x)

-4 = -3x + 14

-18 = -3x

6 = x

So, your missing value is 6. I hope this was helpful and have a grreat rest of your day! ~ Saturns <3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
