Answer:
y = x - 5
Step-by-step explanation:
Given f(0) = - 5 and f(4) = - 3 , then we have the coordinate points
(0, - 5) and (4, - 3)
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 ) = (0, - 5) and (x₂, y₂ ) = (4, - 3)
m = =
=
The line crosses the y- axis at (0, - 5) ⇒ c = - 5
y = f(x) = x - 5 ← equation of line
To find the slope,we can use the point-slope form:
Where m is the slope.
In this case,the equation would be:
-9-2 = m(1-(-3))
-11 = m(1+3)
-11 = 4m
m = -11/4
Therefore the slope is -11/4.
