Changing percent to fraction is an easy thing.
Here is how:
1. Simply put the given number over 100. (Let us have 2%). Drop the percent sign.
2% becomes <u> 2 </u>
100
2. Reduce the fraction into its lowest term.
In reducing its lowest term, we should find their GCF first as their divisor.
2 = 1, 2
100 = 1, 2, 4, 5, 10, 20, 25, 50, 100
Their Greatest Common Factor (GCF) is 2.
3. Divide evenly.<u>
2 </u>÷ <u> 2 </u> = <u> 1 </u>
100 2 50
So, 2% is 1/50 when changed into fraction.
Using the y=mx+b format,
m the slope = (5--9)/(8--12) = 14/20 = 7/10=0.7
y-y1 = m(x-x1)
y-5 = .7(x-8) = .7x-5.6
y = .7x +0.6
10y = 7x + 6
so 7x - 1y = -6 any your equation is almost correct.
Answer:
y = -2x
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = -2x + 3. Its slope is -2. A line parallel to this one will also have a slope of -2.
Plug this value (-2) into your standard point-slope equation of y = mx + b.
y = -2x + b
This question only asks for a line parallel to y = -2x + 3.
This means we can plug in any number (except 3) for b. We cannot plug in 3 because then it will be the same equation!
To make things simple, we can use 0 and therefore leave it out.
y = -2x
This line is parallel to y = -2x + 3.
Hope this helps!
