Find the equation of the line shown
Kipish [7]

Answer:

y = x+1

Step-by-step explanation:

Slope-intercept form

(y = mx+b)

m = slope and b = y-intercept

The line crosses the y-axis at (0, 1), therefore the y-intercept (b) = 1

The slope (m) = 1

Because the slope is 1, it does not need to be written in the equation, as any number multiplied by 1 is that number.
