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:
8
Step-by-step explanation:
Step 1: Set up equation
-1 = 7 - x
Step 2: Subtract 7 on both sides
-8 = -x
Step 3: Divide both sides by -1
x = 8
So 7 subtracted by 8 equals -1.
Answer:
264694796.312
Step-by-step explanation:
A penny is 0.0598 inches (1.52 mm) in thickness. (0.75 is the diamiter).
Hear me out. Now we gotta convert it to miles to divide 250 by the number (there's 6.21371e-7 miles in one mm). first convert the mm to inches (by dividing the length value by 63360). We get 9.444842171717e-7 or 9.44484e-7 for a shorter form. Last step 250/9.444842171717e = 264694796.312.
Oh btw I'm not very sure on this answer correct me please if I'm wrong.
The price of the shirt would drop to $38.40
