Question

Can someone please help

Answer 1

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 $\frac{y}{x}$. 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.
