Answer:
y=mx+b is slope-intercept form
where m is the slope and b is the y intercept.
Since the line crosses the y axis at 0,0 the intercept is +0 or just nothing.
now all we need to do is find the slope
to do that just go from the y intercept (the first point) y units up and x units over untill u cross at the next point. for examples from (0, 0) to (1, 8)-the next point- i need to go up 8 units up and 1 unit over. this is described as rise over run and that is your slope 8/1 rise/run. rise is how many units i go up (or down) from the y intercept until the next point that lies on the line and run is how far i need to go over from how many units i just went up. If u continue to go 8 up and 1 over from each point u will see that u get a point lying of the line. This is why 8/1 is your slope
8/1 is the slope and 0,0 is your y intercept so we put nothing
the equation is y=8x

The probability of not drawing a red marble is 7/10
The probability of drawing a red marble is 3/10
=======================================================
Explanation:
We have 3 red marbles out of 5+2+3 = 10 total. Therefore, the probability of selecting a red marble is 3/10.
The probability of not selecting a red marble is 7/10 because 3/10+7/10 = 1. Put another way, we have 7 marbles that aren't red (the 5 blue and 2 black ones) out of 10 total.
Answer:
8
Step-by-step explanation:
3(8-m)=5m-40
you first distribute 3 through the parenthesis
24-3m=5m-40
Move the variable to the left and change sign
24-3m-5m=-40
now move the constant to the right
-3m-5m=-40-24
collect like terms
-8m=-40-24
-8m=-64
Divide both sides by -8 and negative divide negative number becomes positive
so m = 8

➷ Since vertical angles are equal, we know this:
3x + 50 = 6x - 10
Now we just need to solve for x.
Subtract 3x from both sides:
50 = 3x - 10
Add 10 to both sides:
60 = 3x
Divide both sides by 3:
x = 20
