Answer:
y = -1/2x - 1
Step-by-step explanation:
Given equation:
y = 2x - 3
Given point: (x1,y1) = (-8,3)
This is in the form of y = mx + c,
so, m1 = 2
If the lines are perpendicular then the product of their slope will be - 1 i.e.
m1 x m2 = -1
2 x m2 = -1
m2 = -1/2
Now, using one point form formula,
y - y1 = m(x - x1)
or, y - 3 = -1/2( x - (-8))
or, y-3 = -1/2(x + 8)
or, y = -1/2x - 4 + 3
or, y = -1/2x - 1
This is the required equation.
Answer:
you will need to find the difference (subtract) between two of the y points then do the same for the x points and put to difference of y on top of x and there is you slope using a graph( or if eaven, will come put as a whole number
<span>Part C: Plug in any values for x, get the y values, re-write them as (x,y) coordinates and graph.
Sorry, I do not know the other answers, but Part C was easy</span>

➷ Find the cost per pen by dividing:
300/10 = 30
It costs rs 30 for one pen
1 dozen = 12
2 dozens = 24
Multiply the values:
24 x 30 = 720
The cost of 2 dozen pens is rs 720
However, as it is asking for 'how much more' you have to subtract:
720 - 300 = 420
The cost is rs 420 more
