Answer: y=-13/12x-7
Step-by-step explanation:
To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula 
. We use the two given points to find the slope.
Now that we have our slope, we can start filling out the slope-intercept form equation.
y=mx+b
y=-13/12x+b
Since we don't know the y-intercept, we can use one of the given points and solve for b.
6=(-13/12)(-12)+b [multiply (-13/12) and -12]
6=13+b [subtract both sides by 13]
b=-7
With the y-intercept, we can complete our equation.
y=-13/12x-7
Im pretty sure it would be Ariel.
Tamar reads 600 words in 5 minutes, so he is already out of the question since Levi reads 700 words in 5 minutes. (Levi reads 140 words in 1 minute, so add 140+560=700 because they read 560 in 4 minutes)
So I think it’s Ariel because in 4 minutes she reads 600, and where the 5 would be, if you go straight up, it’s over 700 (if i had to guess, 750 since it’s counting by 100s and it would be in the middle of 700 and 800)
Answer:
10.5 percents
Step-by-step explanation:
1)100+30=130 percents;
2) 130/100*15=19.5percents of discount from the first price
3) 130-19.5=110.5 percents- new price from the initial price
4)110.5-100=10.5 percents - the percentage of profit
