Answer:
Step-by-step explanation:
use the distance formula to determine the distance between two points.
so your answer would be 12
Just isolate x. First you add 16 to both sides, that makes the equation 21=3x. Then divide by 3 and x=7
Answer:
y = -
x + ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (- 1, 4)
m =
=
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 4), then
4 =
+ c ⇒ c = 4 -
= ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
y = -
x +
← equation of line
