Answer:
22.1
Step-by-step explanation:
If we put 65 over 100 and x over 34 and do cross multiplication, we see that 65 times 34 is 2,210. Dividing 100 from both sides of the equation, we divide 100 from x and 100 from 2,210. We are left with X = 22.1
K, so, lets add them up
1+2=3
1+2+3=6
1+2+3+4=10
1+2+3+4+5=15
1+2+3+4+5+6=21
1+2+3+4+5+6+7=28
etc
basically
all numbers 'x' such that
x=
and n is the set of all natural numbers
So to answer this question you first need to find the point slope form and then convert that to slope intercept form.
Point slope form is y-y1 = m(x-x2) where m is slope and (x2,y2) is a point on the line.
Slope is equal to (y2-y1)/(x2-x1). Since you are given two points you simply plug them in!
(7 - - 3)/(3 - - 2) Cancel the double negatives
(7+3)/(3+2) Add what's in parentheses
10/5 Divide
m = 2
Now you can choose either given point to use in your point slope formula. I will be using (3,7) because I wont have to worry about canceling out the negatives.
y - 7 = 2(x - 3)
Now you simply distribute and isolate y to get slope intercept form.
y-7 = 2(x-3) Distribute the 2
y - 7 = 2x - 6 Add 7 to both sides
y = 2x + 1
Since y = mx+b and b is the y intercept. You that you y value when x is zero is 1. This means your final coordinate will be (0,1) or C.
The y-intercept, where it crosses the y-axis, is at 2.
The slope, which is rise over run, is -2.
Therefore, it is the first option. I hope this helps.
