Answer:
B
Step-by-step explanation:
To find the answer, we can use the point-slope form:
Where (x₁, y₁) is a point and m is our slope.
Let's let our point (4, 1/3) be (x₁, y₁) respectively.
We also know that our slope is 3/4. So, substitute 3/4 for m.
This yields:
The choice that represents this is B.
So, our correct answer is B.
And we're done!
Answer:
.
Step-by-step explanation:
On a cartesian plane, the -intercept of a function is the point where the graph of that function intersects with the
-axis.
The -axis of a cartesian plane is the same as the equation
(that is, the collection of all points with an
-coordinate of
.)
Construct a system of two equations, with one equation representing -axis and
to represent the graph of this function:
.
Solve this system for and for
. If a solution exists, then the
-axis and the graph of
would indeed intersect. The point
would be the intersection of the
-axis and the graph of
.
Substitute the second equation of the system into the first.
.
Hence, the intersection of the -axis and the graph of
would be
. By definition, this point would be the
-intercept of
.
