Answer:
y =
x + ![\frac{41}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B41%7D%7B8%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 )
To calculate the slope use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)
m =
=
, hence
y =
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (5, 7 ), then
7 =
+ c ⇒ c = 7 -
= ![\frac{41}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B41%7D%7B8%7D)
y =
x +
← equation in slope-intercept form

Find negative square root of 16. (4 points) a −4 b 4 c ±4 d −8
We need to find 240,000 written as a whole number multiplied by a power of ten.
We need to get rid of the four zeros behind 24 in 240,000.
24 would be our whole number.
We would need to multiply 24 by 10,000 to get 240,000.
10,000 is equal to
because there are 4 zeros. Ex. when multiplying 200 by 30, we first multiply 2 * 3 then we add 3 zeros to the end of 6. So for 10*10*10*10, we add 4 zeros to the end of 1 which equals 10,000.
So the answer would be 24 × ![10^{4}](https://tex.z-dn.net/?f=10%5E%7B4%7D)
