First we have to find the slope formula with the points (0,-7) and (-6,-2). Doing so, we have:
We can see in the graph that the y-intercept is at (0,-7), therefore the equation would be:
y= mx + b (m:slope, b: y-intercept)
y= (-5/6)x - 7 (Replacing)
The answer is y= (-5/6)x - 7
The only sensible answer (from a test-taking point of view) is selection B.
You know the monthly repayment of $1800 over 9 months will be at least $200 per month. Since the interest is about 10% of the loan amount (3/4 of 13.5%), the amount added on for interest will be on the order of $20 per month.
If you work out the math, you find the payment is exactly $220.25 (selection B). You don't need to do that to make a sensible choice.
_____
Payment = ($1800 + 9/12*0.135*1800)/9 = $220.25.
Solve :
1/2(x + 32) = -10....multiply both sides by 2
x + 32 = -10 * 2
x + 32 = -20
x = -20 - 32
x = - 52 <===
check :
1/2(x + 32) = -10.....when x = -52
1/2(-52 + 32) = -10
1/2(-20) = -10
-20/2 = -10
-10 = -10 (correct)
Answer:
It there more to this question because it does not provide the needed information to find what you are looking for.
Step-by-step explanation:
Answer:
Ok so the two points that are given need to be in the form of y2-y1 over x2-x1, meaning the x value from the second set of points needs to be subtracted from the x value from the first set of points, and it is the same for the y values. Then that gives you the slope. You add the slope to the equation y=mx+b. The slope is m, so you put the slope in the m spot. If the slope were 3, it would look like y=3x+b because it is in the m spot. Then, you can choose any 1 set of points given and plug it into the equation. I am going to use the slope 3 , like the last example, and plug it in with the set of points. Say the point was (5,2), you will plug the x value, which is 10 in the situation, next to the the slope. The slope will then be 3(5). Then you will plug in the y value, which is 2, into the y place. At the end, the equation will look like this: 2=3(5)+b. Then you multiply 3 and 5, which is 15, and subtract 2 and 15 which will give you -13. The answer will then be -13=b. That is the y-intercept.
