alisha [4.7K]
I think it’s 25%


Because 70 divided by 10 is 7
Which is then 10% so 20% is 14 then 5% is half of 7 which is 3.5
So 70 -7-7-3.5=52.5 which is 25%

Open-Ended Write an equation for the line in slope intercept form.​
s344n2d4d5 [400]

Answer:

y = -2x+2

Writing the slope was the more difficult part. Writing the y-intercept was the easiest because I had to select to points on the line and solve to get the slope. The y-intercept was already explicitly shown on the line.

Step-by-step explanation:

y = mx+b

y = -2x + 2
