Question

How do i plug in an order pair 3,6 into y=mx+b when m= 1

Answer 1

6 = 1(3) + b

Explanation:

this is following the equation y = mx + b, so you can just take the y and x of the point and plug them into this equation, along with the slope (m)

Answer 2

y = x + 3

Explanation:

Note that: (x , y) = (3 , 6)

Plug in 3 for x, 6 for y, 1 for m

6 = (1)(3) + b

Multiply.

6 = 3 + b

Isolate the variable (b). Note the equal sign, what you do to one side, you do to the other. Subtract 3 from both sides

6 (-3) = 3 (-3) + b

b = 6 - 3

b = 3

Plug in 3 for b

y = 1x + 3

Simplify

y = x + 3

y = x + 3 is your answer
