Answer:

Step-by-step explanation:

(4, 28) (5, 50)

(50 - 28)/(5 - 4)= 22/1 = 22

y - 28 = 22(x - 4)

y - 28 = 22x - 88

y = 22x - 60

Equation for linear function.

y=mx+b

We need 2 sets of numbers from the graph to find the slope. Do rise/run or y/x.

(50-28)/(5-4)=22/1=22

so m=22

y=22x+b

Now substitute x and y in to solve for b

28=4*22+b

-60=b

Now we have the equation all ready.

y=22x-60 Done!

If you have any questions just ask in the comment I will get to it as soon as I could.

*Also although I don't really care about points the points I recieve is half the amount you choose to put in so I got 5 points. Although I honestly don't answer questions for points anyway :)

Find the equation of the line through point (5,1) and perpendicular to 5x−y=−3. Use a forward slash (i.e. "/") for fractions (e.

Y = -1/5x + 2

A line perpendicular to another line has an opposite reciprocal slope. What opposite means is that you flip the sign (from - to + or from + to -) and reciprocal means that you flip the numerator and denominator (so if line A is perpendicular to line B and line As slope is -3, line Bs slope would be 1/3).

First find the slope of 5x - y = -3
Add y to both sides
5x = y - 3
Add 3 to both sides
y = 5x + 3

So the slope of the line is 5. That means the slope of of the perpendicular line is -1/5.

Plug the slope of the perpendicular line and the point (5, 1) into point slope form to solve the equation

y - y1 = m(x - x1)
y - 1 = -1/5(x - 5)
y - 1 = -1/5x + 1
y = -1/5x + 2

So it can be

x=number of flyers

50+0.05x=100

0.05x=50

x=1000 flyers

Hope this helps
