Answer:
the answer to #9 is (½, 1½)
Step-by-step explanation:
to find the midpoint, you need to use the midpoint formula
the midpoint formula is (x₁ + x₂ / 2 , y₁ + y₂ / 2)
for #9 you have to plug in the appropriate numbers in the formula
(-4 + 5 / 2 , 4 - 1 / 2)
(½ , 1½)
Answer:
y=5/3x+7/3
Step-by-step explanation:
Here are the points: (1,4) and (-2, -1)
let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)
label the points:
x1=1
y1=4
x2=-2
y2=-1
now subsitute into the equation
m=(-1-4)/(-2-1)
m=-5/-3
m=5/3
the slope of the line 5/3
Here's the equation so far:
y=5/3x+b (b is a place holder)
we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>
let's use (1,4) as an example
4=5/3(1)+b
4=5/3+b
subtract 5/3 from both sides
7/3=b
Now, put it all together:
y=5/3x+7/3

If the perimeter equals 30 and the length is twice the width, then the length is equal to 20 and the width is equal to 10.
