Write an equation that passes through the points (5, 9) and (2, 6).

y= 1x+4

Step-by-step explanation:

y= mx+b

(y2 - y1) / (x2 - x1)=  6-9/2-5

m= -3/-3

m= 1

we can use either (5, 9) or (2, 6). we'll use (2,6)

6= 1*2+b

6= 2+b

6-2= 2+b-2

4= b

so, y= 1x+4

a

Infinitely many

Step-by-step explanation:

Solve by substitution:

1) Solve for :

2) Substitute for in :

3) Simplify both sides of the equation:

4) Add -2 to both sides of the equation:

5) Simplify both sides of the equation:

Therefore, there are infinitely many solutions.

Solve by elimination:

You cannot solve this system by elimination

Solve by graphing:

The equations are on top of each other, therefore, the system of equations has infinitely many solutions.
