For math- The difference between a value of a variable and another variable which usually ends up to be the variables mean
Answer:
y- intercept = - 2.5
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 = 
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m =
=
= - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5
The value of x will be 23
He spent $52 on sandals. I got this by multiplying 65% by $80 and got $52.
In short answer $52
Its 0 cause 0 divided by any number is 0 but if it was 15/0, then it would be undefined
