Which order pairs in the form (x, y) are solutions to the equation 7x - 5y =28? select each correct answer. (-1, -7) (-6, -14) (4,10) (7,9)

(-1, -7) True

(-6, -14) True

(4,10) False

(7,9) False

Step-by-step explanation:

Problem One

1. Multiply the numbers

7(-1) - 5(-7) =28

2. Calculate

-7+25=28

3. Check the equality

28=28

True

Problem Two

1. Multiply the numbers

7(-6) - 5(-14) =28

2. Calculate

-42+70=28

3. Check the equality

28=28

True

Problem Three

1. Multiply the numbers

7(4) - 5(10) =28

2. Cancel equal terms

28=-50=28

3. check for equality

-50=0

False

Problem Four

1. Multiply the numbers

7(7) - 5(9) =28

2. Subtract the numbers

49-45=28

3. Check for equality

4=28

False

i hate black

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
