Answer:
f(x) = -2/15x + 14/15
Step-by-step explanation:
Slope = (2/3 - 4/5)/(2 - 1)
= (10/15 - 12/15) = -2/15
Plug in a known point (into y=mx+b) to find y-intercept:
4/5 = -2/15(1) + b
12/15 = -2/15 + b
b = 14/15
Formulate:
f(x) = -2/15x + 14/15
Point-slope form is : y-y₁=m(x-x₁)
The points given are : (8, -4)
Slope given : -5/6
So, simply plug in the values.
Remember, m = slope
y - y₁ = m(x - x₁)
y - (-4) = -5/6(x - 8)
Simplify.
y + 4 = -5/6(x - 8)
So, your answer is the THIRD choice.
~Hope I helped!~
You spent 9 dollars. why? because your neighbor spent 3 times more than you, which means you spent 1/3 of what he spent. so just multiply by 1/3 to get 9.
this can also be modeled by an equation. 3x = 27
divide 3 on both sides to get
x = 9
Answer:
2 is your slope
Step-by-step explanation:
Find the slope. Use the slope-formula:
<em>m</em> (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-1 , 1)
(x₂ , y₂) = (2 , 7)
Plug in the corresponding numbers to the corresponding variables:
<em>m </em>= (7 - 1)/(2 - (-1))
Simplify:
<em>m</em> = (6)/(2 + 1)
<em>m</em> = 6/3
<em>m </em>= 2
2 is your slope (or <em>rise</em> 2, <em>run </em>1).
