Isosceles triangle
so
x + 8 = 2x -1
x = 9
BC = 3x - 3
BC = 3(9) - 3
BC = 27 - 3
BC = 24
No because they are not following the same rule
Answer:
y =
x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m =
, then
y =
x +c ← is the partial equation
To find c substitute (- 4, - 3) into the partial equation
- 3 = - 3 + c ⇒ c = - 3 + 3 = 0
y =
x ← equation of line
Put the number over each the total that was added then, divide the bottom number to into the top number
Answer:

Step-by-step explanation:
We have two coordinate points and are asked to find a slope.
When finding slope, we can use the formula listed :

To understand what the variables are, you can take this :


Substitute the points :


Now substitute it into the formula :
