Use point-slope form.
But first let's find the slope.
(4, 2), (2, 4)
m = y2-y1/x2-x1
m = (4 - 2)/(2 - 4)
m = 2/-2
m = -1
So this is the slope, now we can plug this into the equation along with any point.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Let's plug in point (4, 2):
y - 2 = -1(x - 4)
This can be one of your options.
Distribute -1:
y - 2 = -x + 4
Add 2 to both sides:
y = -x + 6
This can be another of your options.
Add 'x' to both sides:
x + y = 6
This can be another of your options.
Answer:
m<-2
Step-by-step explanation:
-4m-3.65>4.35
-4m>4.35+3.65
-4m>8
4m<-8 (the greater than or less than sign flips when you multiply or divide by the - sign)
m<-2 (divide both sides by 4)
I believe you go to the spots on the graph and then just found up from there, and do that with every point
