What’s the slope and y-intercept of y=x?

Slope is 1; y-int is (0, 0)

Step-by-step explanation:

Step 1:  Identify the slope

The slope is the number attached to the x.  Since in this problem there is no number or sign, that means that number in front of it is 1.

y = 1x is same as y = x

So... the slope is 1

Step 2:   Identify the y-int

The y-int is the number after the mx, also known as b.  In this problem there is no number after, that means that the y-int is 0.

y = mx + b

y = 1x + 0

So... the y-int is (0, 0)

 Slope is 1; y-int is (0, 0)

step-by-step explanation:

first, eliminate the parenthesis:
