First you need to find the slope, which is (y2-y1)/(x2-x1)
Plug the points in as (1-4)/(-1-1) -> -3/-2
The slope is 3/2, or 1.5
Point slope form is y-y1 = m(x-x1)
Plug in the slope (m) and the first point
y-4 = 1.5(x-1) <-- That's point slope form
To get standard form (ax+by=c), you can use point slope form
y - 4 = 1.5(x - 1)
y - 4 = 1.5x - 1.5
y = 1.5x + 2.5
-1.5x + y = 2.5 <-- Standard Form
I am guessing there is half of each type of book, so there are 50/100 or 1/2 that are fiction
hope this helped
Answer:
.
Step-by-step explanation:
Answer:
<h2>x=2 y=6</h2>
Step-by-step explanation:
x+y= 8
there are lots of pairs
y= 2x+2
there are lots of possibilities
but if
x+y=8 when y= 2x+2
then you plot both of these lines on a graph
you can do this by replacing
x by other numbers in both of the equations
i have done this and i found out x=2 and y=6
Im pretty sure the answer is D
