Whats the slope of a line if its plotted (0,0) and (3,6), find the y-intercept of the line. write an equation for the line using your answers. find one more point that lies on the line. explain why that point is also a solution to the function. ( explain your answers so i could understand it more) guys!

To find the slope you do the method
Y2-Y1

X2-X1
So you do 6-0=6 and 3-0=3. That would be 6/3 and then, you simplify it. Your slope is 2.
To find the y-intercept you have to do the point slope form, then, you do the slope intercept form
Y-Y1=m(x-x1)
You do y-6=2(x-3)
Y-6=2x+(-6)
You add six to both sides
The equation is y=2x
The y-intercept is -6
One more point on the line would be (4,8). Because if you look at the slope it is 2/1. When plotting a point you look at the slope as rise over run. The two is the rise and the 1 is the run. So you go to (3,6) and add 1 to the 3. Then, you add 2 to the 6 to get (4,8). That's why that point is a solution to the function. You could also do (2,4) if you did the opposite and subtracted the 2 and 1 to make the bottom half of the line.

Very simple.

so slope=rise/run so if we plot the points and find how high and how long it went we see that the slope=6/3=2
slope=2

since the line goes through the origin (0,0) the y-intercept=(0,0)
and the equation is
y=mx+b
m=slope
b=how much away from the origin whic is not applicable in this problem. so
y=2x

Answer from: Quest

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

$\frac{1}{4}=\frac{x}{5}\\\\x=\frac{4}{5}\\\\x=0.8$

hence, first option 'a' is correct.
