Answer:
The slope of this line is -1/2
Step-by-step explanation:
To find the slope of any equation, we need to use the slope formula.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-13 - -15)/(11 - 17)
m = (-12 + 15)/(11 - 17)
m = 3/-6
m = -1/2

Answer:
So identifying this problem,3 times 3 is 9.Then 9 divided by 4 equals 2.25.To give you an answer of (2.25+9).
Step-by-step explanation:
Answer:
So we have x+3 if -3<=x<=-1
and 5 if -1<=x<=1
Step-by-step explanation:
The one piece from -1 to 1 is horizontal so the line is in the form of y=a number. It goes through 5 on the y-axis so the equation there is y=5.
From -3 to -1, that is a line with positive slope (since that part is increasing).
Slope=rise/run
We see from the filled in dot to the unfilled in dot that the rise is 2 and the run is 2 so the slope is 2/2=1.
So if we did extend this line where we go at on the y-axis? It would go through 3 because starting from the unfilled dot and rising 1 and running 1 will get us to the 3 on the y-axis.
The equation of a line in slope-intercept form is y=mx+b.
We have m=1 and b=3 so the equation is y=1x+3 or just y=x+3.
So we have x+3 if -3<=x<=-1
and 5 if -1<=x<=1
A function is a rule that assigns each value of the independent variable to exactly ONE value of the dependant variable
