How do i find the slope and y intercept ?

Here are the instructions. Then we'll do your specific problem.

Step 1: Solve the equation for y, and write it in the form y = mx + b.

Step 2: The slope is m, and the y-intercept is b.

Now let's start.

-2x - 5y = -20

To solve for y, we first add 2x to both sides.

-5y = 2x - 20

Now we divide both sides by -5.

Now we compare what we got with the form, y = mx + b.

We see that m = -2/5, and b = 4. m is the slope, and b is the y-intercept.

slope: -2/5

y-intercept: 4
