is that enough to pay the $1100?

now, let's write 1000(1+r)² in standard form

1000( 1² + 2r + r²)

1000(1 + 2r + r²)

1000 + 2000r + 1000r²

1000r² + 2000r + 1000 <---- standard form.

Graph the function y=2x+3

stealth61 [152]

I will show how to do it:

Step 1: Start your point at 3 in the y axis (line going upwards)

Step 2: Move up twice.

Step 3: Now go to the right once.

Step 4: Use a ruler to draw the line.

Step 5: Cross check by picking two points that are on the line. Or use the formula - y2 - y1 / x2 - x1
