Hi there!
I'm guessing you want to know what the equation of the slope-intercept line is.
The general equation for the slope-intercept line looks like this:
y = mx + b
Where "m" is the slope and "b" is the y-intercept.
Since we know what the slope is and we have the coordinates of a point, you can replace the slope and the value of the coordinates "x" & "y" in the equation and solve for "b" in order to find the whole equation :
y = mx + b
-1 = -1/2(10) + b
subtract "b" from each side of the equation
-1 - b = -1/2(10)
Add 1 to each side of the equation
-b = -1/2(10) + 1
-b = -5 + 1
-b = -4
Divide each side of the equation by -1
b = 4
Since you now know the value of "b" you can go ahead and write the slope-intercept equation with the slope in it and the y-intercept value also (b) :
y = -1/2 + 4
There you go! I really hope this helped, if there's anything just let me know! :)

Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
Let x= width
Then x+3= length
So 2x+2x+6=26
4x+20
x=5
Width is x=5m and length is x+3=8m
Area is (lenght)(width) so (5)(8)= 40m squared
Answer: P represents -13
Step-by-step explanation:
Since a negative x negative + positive, we know that p has to be a negative.
For me, I added both 21 and -5 (though I made it into a positive), and got 26.
What number times -2 is positive 26?
So, you divide 26/-2, which then becomes -13.
Thus, p=-13 :)
