What is the function with a rate of change of 3/2 whose graph passes through the point (4, 10.5)?
1 answer:
<h2>Answer:</h2>
y= *x+4.5
We are given a slope and a point. That is why we will use point slope form.
The default equation is:
(y-a)=m*(x-b)
a is the y coordinate of our point and b is the x coordinate of our point
m is the slope.
We will plug in the values.
(y-10.5)=3/2*(x-4)
Now we just manipulate the equation
y= *x+4.5

Answer:
y = - x - 3
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 ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line
m = = -
Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = - x - 3 ← equation of line
