Help with this math problem please.

Slope is -2 and equation is y=-2x+1

Step-by-step explanation:

Slope is the rise over run from one point to another. The points are (0, 1) and (1, -1) and to get from (0, 1) to (1, -1), you have to move down 2 times and go to the right 1 time. That would be -2/1 which is just -2 for the slope.

To make the equation you fill in what you already have. Y=Mx+b. m=slope so m=-2 and b=y-intercept so whatever’s on the y-axis is b. B=1. Y=-2x+1.

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!

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
