Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
Given Points are (8 , 30) and (18 , 60)
here x₁ = 8 and x₂ = 18 and y₁ = 30 and y₂ = 60
We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)
Here the line passes through the point (8 , 30)
⇒ x₀ = 8 and y₀ = 30
We found Slope(m) = 3
Substituting all the values in the standard form, We get :
Equation of the line : y - 30 = 3(x - 8)
Let d be the x-intercept of this line
⇒ The line passes through the point (d , 0) as at x-intercept, y-coordinate is zero.
⇒ 0 - 30 = 3(d - 8)
⇒ 3d - 24 = -30
⇒ 3d = -30 + 24
⇒ 3d = -6
⇒ d = -2
⇒ The x - coordinate of the x-intercept of the line is -2
Answer:
y=2
Step-by-step explanation:
15y+5y-19y+2=4
y+2=4 Add similar elements
y+2-2=4-2 Subtract 2 from both sides
y=2 Simplify
Answer:
78.12
Step-by-step explanation:
Answer:
Cost for 13 rides: $92
Cost for r rides: I am guessing it would be 40+4r
Step-by-step explanation:
If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
Answer:
C
Step-by-step explanation:
This was a bias, because in the location, there must have been a greater concentration of basketball fans than fans of any other sport.
Hope this helped.
