Answer:
16/75 = .2133 or 21.33%
23/90 = .255 or 25.55%
13/15 = .866 or 86.66%
11/90 = .122 or 12.22%
Step-by-step explanation:
We know that to find the percent of a number you must multiply the percent by the number like this:
23% of 60
.23 x 60 = 13.8
Now to go backwards all you have to do is divide back. So for instance if we wanted to find now what percent 13.8 is of 60, we would divide 13.8/60 and get .23.
So for these just divide all the first numbers by the second numbers:
16/75 = .2133 or 21.33%
23/90 = .255 or 25.55%
13/15 = .866 or 86.66%
11/90 = .122 or 12.22%
hope this helps!
Find slope
(y2-y1)/(x2-x1) is slope
(11-3)/(1-(-1))=8/2=4
y=4x+b
input a point
(1,11)
x=1
y=11
11=4(1)+b
11=4+b
minus 4 from both sides
7=b
the equatin is
y=4x+7
the closest one
minus 4x from both sides
y-4x=7
times everybody by -1
4x-y=-7
last choice is answer

Answer:
y = 2x + 4
Step-by-step explanation:
You already know the slope, so now you need to find the y-intercept. You need to plug in the values of x and y into the equation, y = 2x + b.
y = 2x + b
2 = 2(-1) + b
2 = -2 + b
4 = b
