Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)
m = =
=
Use either of the 2 points for (a, b)
Using (a, b) = (- 4, - 1), then
y - (- 1) = ( x - (- 4)), that is
y + 1 = (x + 4)
Answer:
The equation that models the relationships between , the number of hours Mark reads, and ,
the number of pages of the book he reads is:
Step-by-step explanation:
Given:
Mark reads 42 pages every hour.
The number of hours is given by =
The number of pages is given by =
The equation can be modeled as:
where represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value as Mark starts reading from 0.
So, the equation is:
