Answer:
The slope is 3/2.
Step-by-step explanation:
The slope of a line is the relationship between the change of the y-variable and the change of the x-variable. It can be denoted as m = (y2-y1)/(x2-x1), and in layman's terms, it is known as rise over run.
You always can obtain the slope of a line with two points. From this line, for example, I can tell that points (0, 20) and (20, 50) are on the line.
To find the slope of the line, we must first find out what x1, x2, y1, and y2 are. x1 and y1 are the x- and y- coordinates of the first point, and x2 and y2 are the x- and y-coordinates of the second point. With this, we now know that x1 = 0, y1 = 20, x2 = 20, and y2 = 50. We now subsitute this into the formula.
m = (y2-y1)/(x2-x1)
m = (50 - 20)/(20 - 0)
m = (30)/(20)
m = 3/2
Now we know that the slope of the line is 3/2.
Y=5x I think. Hope this helps
Answer:
Carol has only 20p and 10p coins in her purse.
She has three times as many 20p coins as 10p coins. If Carol has £4.20 altogether, how many 20p coins does she have?
Answer:
Let's define the variables:
M = number of books that Marcus has.
x = number of books that Jessie has.
We know that:
"Marcus has one book less than three times the number of books that Jessie has."
Then the equation that represents the number of books that Marcus has is:
M = 3*x - 1.
Then if x tiles represent the number of books that Jessie has, the number of tiles for Marcus will be 3 times that, and then subtract one tile.
