I think that the mean is 6 5/8 and i think that the median is 5 3/4
(-3/2, 27\4) is the vertex it opens down max at the vertex mins are negative infiity x intercepts at -1 and 3 y intercept at (0,0)
Answer:
y= mx+c
-4= -3/5(-5) + c
-4= -3/5 *-5+ c
-4=3+c
-4-3=c
-7=c
therefore the equation of the line is y=-3/5x-7
Step-by-step explanation:
the equation of a line is
y=mx +c
where y is the y coordinate
where m is the slope
where x is the x coordinate
where c is the y- intercept
This is in the fourth quadrant where the cosine is positive
By pythagoras the hypotenuse is 5
so the cosine is 3/5 B
