Answer:
y = -1/2x + 1
Step-by-step explanation:
in order to find the slope, you use rise/run.
for example,the point on (-2,2) and the point on (-4,3) goes UP (rise) by 1, and goes ACROSS (run) by 2.
this means that the slope of the line is -1/2x.
next, you need to find the y-intercept.
the y-intercept is the point on the Y line on the graph.
for this line, that point is 1.
the y-int is 1.
y=mx+b
mx = slope
b = y-int
Answer:
-1 or 1 yes because -1 is greater because it is a greater number than -2
When put in a calculator, the answer is 12.22 (recurring)
You'll actually need to graph for the first segment
but the second part can be solved with algebra
The equation of the line is y(x)=-x
if we test the co0ordinates we can find if the point lies on the line
(5,5)
y(x)=-x
Using the x co-ordinate
y(5)= -5
y=-5
Leaving us with (5,-5)
Because (5,-5) is not (5,5)
This is not a point on the line
The slope of the line is -1
