I’ll mark you brainlist write in y=mx+b form

Step-by-step explanation:

The rate of change is the same as the slope (m variable), and in this sense you don't have to write out -1x, you can just keep it at -x. The point you are given is the point where the line crosses the y axis, which is called the y-intercept and is the variable b in your equation. This is because the x coordinate is zero, so it has to be where the line crosses the y axis. Just put that -4 in as your b variable, and there's your answer!

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
