Answer:
Step-by-step explanation:
The vertical asymptotes need to be in the denominator. They become VA's when that small expression value equals zero.
x=-2 will become (x+2)
and x=-6 will become (x+6)
The x intercepts will be in the numerator.
x=-1 will go with (x+1) and x=3 will go with (x-3)
The horizontal A must be the quotient of the coefficient of the numerator and denominator, since both the top and bottom have the same power.
To make the quotient 7, we place a seven in the numerator so 7/1=7.
To find the line, you need to use the point-slope formula because you're given both the slope and a point.
y - y₁ = m(x - x₁)
m = -2/5
x₁ = 10
y₁ = 3
y - 3 = -2/5(x - 10)
y - 3 = -2/5x + 4
y = -2/5x + 1
y = -2/5x + 1 is the line.
Y=5x
Explanation:
You would take two points and use the slope formula
Y2-y1/x2-x1
So I took the points (0,0) and (1,5)
5-0/1-0
5/1
5= the slope
So now we know y=5x+b and since it shows us on the graph where the line crosses the y axis we know the y intercept will be zero because it crosses at 0. When the y-intercept is 0 we don’t even need to list it.
A yard stick would be used
The square root of 25, is 5.
