Y=-3x+36 because the line crosses the y axis at 36
Answer:
y = 1.5x
Step-by-step explanation:
We are to find the equation of the straight line
Using the coordinate (0, 0) and (200, 300)
Slope m = 300-0/200-0
m = 300/200
m = 1.5
Since the line pass through the origin, the y intercept is 0
Substitute m = 1.5 and b =0 into y = mx+b
y = 1.5x + 0
y = 1.5x
This gives the required equation
Students in 2014 = (100% + 33%) × 2,300
students in 2014 = 133% × 2,300
students in 2014 = 133/100 × 2,300
students in 2014 = 3,059
There are 3,059 students in 2014
The first integer is going to be x and the second one is going to be y.
We now turn the clues into equations:
x = y - 5
xy = 84
The substitution method:
(y - 5)y = 84
y^2 - 5y - 84 = 0
(y+7)(y-12) = 0
y = -7, 12.
If y = -7, then x = -12.
If y = 12, then x = 7
