What is a point-slope equation of the line through the points (−1, −5) and (−2, 4)?
a) y + 5 = −9(x + 1)
b) y − 4 = 9(x − 2)
c) y − 5 = −9(x − 1)
d) y − 4 = 9(x + 2)

what is the standard form of the equation of the line whose slope is −2 and which contains the point (3, −5)?
a) 2x + y = 1
b) 2x + y = −8
c) 2x + y = 11
d) 2x + y = −7

if you could provide the work to so i can know what you did i would really appreciate it,

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!

so, converting firstly the mixed fractions to improper fractions and then "adding".

the answer is b

sorry

sorry, but im pretty sure its a now that i look at it
