I will explain how to get the solution using the text and look at the image as well as I’m using it to explain my process.
Step 1: Write the equation for slope-intercept form which is y=mx + b
Step 2: FIND SLOPE. M means slope in mathematics and the formula for that is rise divided by run. Which actually means y2 - y 1 divided by x2 - x1. If you are wondering what those are, they are points in the graph. It doesn’t matter which point you choose but you’ll see which ones I chose in the image. Follow the steps there
Step 3: FIND Y INTERCEPT: this step is easy because you are provided with a graph so you don’t have to find the y intercept algebraically. The y intercept is where the graph touch’s the y axis. In your case, it is at -4.
Step 4: CREATE THE EQUATION.
Refer to step one and re write the equation for slope intercept form: y=mx + b. Replace m with -2 and b with -4. So your equation looks like this: y= -2x -4
Answer:
endless solutions they have y=x-1 hopefully that helps you out with your question
Answer:
$16.99
Step-by-step explanation:
The first step into solving this requires you to find out what 15% of $19.99 is. In order to do that, you must multiply the number (19.99) by the decimal form of the percentile (15%). To find a decimal form of a percent sign, you must simply move the decimal two spots to the left, to change the denominator to 100. A number always has a denominator, even if it isn't shown. in this case, it is 15/1, and we have to convert it to 15/100 so all you have to do is divide 15 by 100, or move the decimal to the left 2 spots. The answer you should get is 0.15
I normally don't round until I have the <em>final</em> answer, just so the numbers aren't off. So then, what you need to do, is multiply 19.99 by your newly found decimal. You should get 2.9985. Now, the question asks for how much the cartridge would cost if it were 15% off, so therefore you must subtract your answer from the original number (19.99), and should get 16.9915. Now is the time you should simplify to the nearest hundredth, and should get $16.99 as your final answer.
