Answer:
The equation that would represent it would be y - 1 = (x - 5)
Step-by-step explanation:
In order to get this, we can start with the base form of point-slope form.
y - y1 = m(x - x1)
Now put the point in for (x1, y1)
y - 1 = (x - 5)
Answer:
=3
=−2
Step-by-step explanation:
Start with y=mx+b
B is your y intercept
m is your slope
The points you have are (-1,4) and (1,-2)
To find the slow you Do Y2-Y1/X2-X1
(-2-4)/ (-1-1)
-6/-2
your m is 3
Now you go back to the equation of a Line y=mx+b
to find b (your y intercept) take on of the two points, and substitute it's y value in the equation Let's take (1,-2)
Y=mx+b
-2=3(1)+b
-2=3+b
b=-5
you now know that
b=-5
m=3x
The equation is
y=3x-5
Answer:
See screenshot for graph and points - This is <em>not</em> a function because it fails the vertical line test.
Step-by-step explanation:
The vertical line test means that if you can draw a vertical line anywhere on the graph and it hits more than one part of the graph, then it isn't a function.
$1500!
20% off of $1500 would be $300. $1500 - $300 = $1200. Therefore the original sales price was $1500!
