Answer:
Slope: -1/3
Y-intercept: -6
Step-by-step explanation:
x + 3y = -18
x+18 = 3y
-3y/-3 = x/-3+18/-3
y = -1/3x - 6
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
Ok y is your y value from any point on the graph m is your slope x is the x value of any point from the graph and b is your y intercept that is where the line cross in the y line that is the vertical line in the graph
Answer:
Add 1 to both sides of the equation.
Subtract 3 from both sides of the equation.
Step-by-step explanation:
The inverse of a function refers to that function that tends to undo another function.
If we intend to find the inverse of the function, f(x) = 3+ V2 - 1, we have to first add 1 to both sides of the equation and subsequently subtract 3 from both sides of the equation before taking the square root of both sides to obtain the inverse function.
