Graph the linear equation with the given slope and y-intercept:
galina1969 [7]

Answer:

Step-by-step explanation:

the y intercept determines where you are going to start and then your m or your slope tells you how many units up or down and left and right you are going to go or you rise over run in this case 2/1

so you start at (0,2) and then move 2 up and one to the right

and you go 2 units down and 1 to the left

Can anyone figure this out ??
Nookie1986 [14]
ANSWER:

The solution for this problem is displayed in the attached image. I have made the numbers ( answers ) which I inputed into the table bold and red.

The method I used to solve this problem was trial and error.

To check the answers, you must simply input the numbers with each of the symbols into the equations. If the left-hand side of the equation is equivalent to the right-hand side of the equation, the equation is correct.

COLUMNS -

Column No. 1:
5 + 4 - 7 = 2
9 - 7 = 2
2 = 2
Therefore, this equation is correct.

Column No. 2:
9 ÷ 1 + 6 = 15
9 + 6 = 15
15 = 15
Therefore, this equation is correct.

Column No. 3:
3 × 8 ÷ 2 = 12
24 ÷ 2 = 12
12 = 12
Therefore, this equation is correct.

ROWS -

Row No. 1:
5 × 9 ÷ 3 = 15
45 ÷ 3 = 15
15 = 15
Therefore, this equation is correct.

Row No. 2:
4 - 1 × 8 = 24
3 × 8 = 24
24 = 24
Therefore, this equation is correct.

Row No. 3:
7 - 6 + 2 = 3
1 + 2 = 3
3 = 3
Therefore, this equation is correct.

Since all equations in this problem are correct, this means that all the numbers ( answers ) must also be correct.
