The number of cans needed to paint an area covering 2,200 sq. units will be given by:
number of cans=[area required to be painted]/[area that 1 can of paint can cover]
=2200/400
=5.5
Therefore we conclude that we will need 5.5 cans of paint
It is point slope
y-y1 = m(x-x1)
y1 = 2, m = -1, x1 = -3
Make it into slope intercept
Y = -1x + b
2 = 3 + b, b = -1
Y = -1x - 1
Find three points
(-3, 2), (-1, 0), (0, -1)
Now plot these points and draw a line through them
Given:
The equation of a straight line is

The x value of a point on the line is 14.
To find:
The y value of this point.
Solution:
If a point (x,y) lines on line, then the equation of line must be stratified by that point.
We have, the equation of a straight line.

Putting x=14, we get


Therefore, the y-value is 6 when the x-value is 14.
Hi there!

Hope this helps you. I apologize if it’s incorrect.
Im not rlly sure about this it seems confusing
