The slope is 1.

The y-intercept is at (0, 1).

Explanation:

y+1=1(x+2)

This equation is in point-slope form:

Based on the picture, we know that the slope is the value multiplying xx1, so the slope is 1.

To find the y-intercept, plug in 0 for x and solve for y:
y+1=1(x+2)

y+1=1(0+2)

y+1=2

y=1

Therefore, the y-intercept is at (0,1).

Slope 1, y-intercept of 1

Explanation:

It may be more intuitive by converting this equation into slope-intercept form

y=mx+b, with slope m and a y-intercept of b. Let's start by distributing the 1 on the right to get

y+1=x+2

Next, let's subtract 1 from both sides to get

y=x+1

We see that our slope is 1, and so is our y-intercept.

Hope this helps!
