Answer:
The equation is:
y= -2x + 3
Step-by-step explanation:
There are two ways to solve this:
You could do very long algebra but you could also just plug in your information and make life easy for yourself.
Start of by plugging in your slope into the equation. (due to y=mx+b, m= slope=-2 )
y= -2x + _
Then plug in the co-ordinates give.
(1) = -2(1) + z
Then solve for z
1 = -2 +z
+2 +2
z= 3
Then plug all your information in to get
y= -2x +3

To find the product of a reasonable estimate of two decimal numbers, round each decimals to the nearest whole number and then perform the multiplication.
For example:
3.2 x 5.7
Estimated answer
3.2 will be rounded down to 3 and 5.7 will be rounded up to 6
⇒ 3 x 6 = 18
Actual Answer
3.2 x 5.7
=18.24
