Step-by-step explanation:
You have to subtract 2 1/2 from 6 and that will equal 3 and 1/2.
I hope this helps! It’s been a while since I’ve done slope-intercept though, so I might be a little rusty
For slope, people sometimes use the description 'rise divided by run'. We know that the y axis describes rise, and the x axis describes run. So rise divided by run written numerically is . Now let's look at the line above. We can see that every time the y value goes up one unit, the x value goes right two units. This means that [tex]\frac{y}{x} --> \frac{y + 1}{x + 2}
This can be rewritten as 1/2, so the is 1/2. Hope this helped.
