Hey there!
Use the slope formula.
m= (y2-y1)/(x2-x1)
Plug in the points. (-4,5) and (4,1)
m= (1-5)/(4-(-4)
m= -4/4+4
m=-4/8
m=-1/2
To find the y-intercept, first plug it into the the point slope. You just need one set of points for this, I will use (4,1)
y-y1=m(x-x1)
y-1= -1/2(x-4)
y-1=-1/2x+2
Add 1 to the other side.
y= -1/2x+3
The 3 is your y-intercept. It is in slope intercept form now. (y=mx+b) The b is the y-intercept.
The equation of the line is usually represented by the slope intercept form, which you already have: y=-1/2x+3.
I hope this helps!

Answer:
20/4
Step-by-step explanation:
10/2 = 20/4
Morgan can write 6 pages in 3/4 of an hour.
1/4 of the population is A+
if you wanted 5/9 to have that blood type you would need to make an equation using 1/4 and 5/9.
5/9 x 1/4 = 5/36 or 0.139
You can verify because of all 9 had the A+ you can do the same equation but with 9/9 and 1/4
9/9 x 1/4 = 9/36 which is 0.25 or 1/4
