Answer:
1/2
Step-by-step explanation:
The formula for slope is (y2 - y1)/(x2-x1)
In this case, it is (2 - 1/2)/(4-1) which is 1.5 over 3. The slope is 1/2
y = 10x + 5 is the required equation.
Explanation:
A family of two to go to state fair is $25
A family of six to go to state fair is $65
So the 2 points are (2,25) and (6,65)
Rate of change = (y2-y1)/ (x2-x1)
Plugin the values, we will get,
= (65 - 25)/ (6-2)= 40/4 = 10
Equation can be written as,
(y - y₁) / (y₂ - y₁) = (x-x₁)/(x₂-x₁)
(y-25)/(65-25) = (x-2)/(6-2)
(y-25)/ 40 = (x-2) / 4
4(y-25) = 40(x-2)
4y - 100 = 40x - 80
4y = 40x - 80 + 100
4y = 40x + 20
Dividing the equation by 4, we will get,
y = 10x + 5 is the equation required.
Answer:
Coordinate of K: (3, 1)
Step-by-step explanation:
The rule
(x + 1, y + 5) tells us
Add 1 to x point (coordinate)
and
Add 5 to y point (coordinate)
Lets look at the diagram and figure out the coordinates of K:
From origin, we go 2 units right and 4 units down, so coordinate of K is:
(2, -4)
Now we apply the rule:
(2 + 1, -4 + 5)
= (3, 1)
The new coordinates of K will be:
<u>(3, 1)</u>
