Identify the slope and the y-intercept of each line.

I need a picture or an example to help you. To identify the slope and y-intercept you have to do slope intercept form. Y=mx+ b or y=slope+ y intercept. If you are looking at a graph then, the y intercept is the only point on the y axis. To find the slope on a graph you have to count how much the point rises and moves from each point. Like, if my point was (1,3) and the next point was (3,4). To get to (3,4) you would have to go up 1 and move 3 spaces to the right. Your slope would be 1/3.

$9500 is invested part of it at 12% and part of it at 9%, for a certain year the total yield is $1032.00. How much was invest at

svet-max [94.6K]

so what i did was a long process but it worked i started by taking $5550 and multiplying it by .12 which gave me $666 then i did 9500-5550=3950 then i took 3950 and multiplied it by .09 and it gave me 355.5 then i added those together and got 1021.5 so i needed to increase the amount i invested at 12% to get a higher yield. i did this process a few more times and each time i increase the amount of money i invested at 12% by 25 dollars and i finally arrived at:

5900 x .12 = $708

9500-5900=3600

3600 x .09 =$324

708+324= $1032

so your answer is that you invested $5900 at 12% and $3600 at 9%.

add me as a friend if you like because i am generally good at math. hope this helped.
