slope intercept form
y -y1 = m(x-x1)
y-3 =1/4 (x-4)
distribute
y-3 =1/4 x-1
stand form of a line is Ax +by =c
so subtract 1/4 x from each side
y -3 -1/4 x =-1
add 3 to each side
y-1/4 x =2
-1/4 x +y =2
I would multiply by -4 on both sides to make the 1st term positive and get rid of the fraction
x -4y = -8
Find the slope of the line that crosses through the points (-3, -4) and (2, -3).
slope = (y2-y1)/(x2-x1)
m = (-3--4)/(2--3)
m = (-3+4)/(2+3)
m =(1/5)
m=1/5
If the number is a positive negative fraction improper fraction or mixed number
The area formula of a circle is π×
pi is 3.14 and r is the radius. The question gives you the diameter. To find the radius with a given diameter, divide the diameter by 2. 24÷2=12. The radius is 12. Now we can multiply 3.14×
do the exponents first. 12×12=144. Now multiply that by pi. 144×3.14=452.16
