Answer:
The line is y=1x+8
Step-by-step explanation:
We can use point-slope form of a line to make an equation. Point-slope form is as follows:
y-y₁=m(x-x₁)
**The variables y₁ and x₁ are where we will plug in our given coordinates and the variable m is your slope.
1. Plug in the given info:
y-10=1(x-2)
2. Distribute the 1:
y-10=1x-2
3. Add 10 to both sides:
y=1x+8

Answer:
-1/2 is your answer.
Step-by-step explanation:
The slope formula is (y_2 - y_1)/(x_2 - x_1)
The y's are -3 and 2, while the x's are 9 and -1.
(-3-2)/(9-(-1))=-5/10=
-1/2 is your answer.
Answer:
I would divide the one whole part in multiple parts such as making a bunch of the little triangles and finding the area of the those then add them all up to get the total perimeter.
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
the altitude creates two congruent 30-60-90° triangles
the ratio of the sides in a 30-60-90°, respectively, are 1 : : 2
therefore we can set up a proportion to find the side length:
let 'x' = side length of equilateral Δ
/ 1 = 21 / x
cross-multiply:
x = 21
x = 21 /
rationalize the denominator by multiplying numerator and denominator by
21 / · = 21 / 3 or 7
