Hint: Here, we will first find the points of the graph by substituting some value of in the given equation to find the corresponding value of . We will then substitute some value of to find the corresponding value of , this will give us another set of points. We will then draw the graph of the given equation by using these two points. We will mark these points on the graph and connect them by a straight line.
Complete step-by-step answer:
The given equation is .
We observe from this equation that the powers of and are both one. So, the given equation is a linear equation.
The graph of a linear equation is always a straight line.
We will first find two points lying on the graph of the given linear equation. These two points should satisfy the given linear equation.
Let us rewrite the given equation as .
Now we will substitute in the given equation and find the value of . Therefore, we get
We see that when , we get . So, one point is .
To find another point, we will put .
Adding the terms, we get
In this case, we get .
So, the second point is .
Using these points, we will draw the graph of .
The point will lie on the negative -axis and the coordinate is zero. The point will lie in the first quadrant because both and coordinates are positive.
Therefore, we get the graph as follows:
Note: Another method to draw the graph is by slope-intercept form.
We shall compare the given linear equation to the slope-intercept form of a linear equation. The slope-intercept form , where is the slope of the line and is the intercept, i.e., the point where the graph cuts the axis.
Comparing the equation with , we get
.
Here the slope is 4 and the intercept is .
First, we have to mark the intercept.
Since, the intercept is negative, i.e., , it will lie on the negative axis.
Now, the slope is 4, which can be written as .
Here the numerator 4 means we have to go 4 units up the point and the denominator 1 means we have to go right by 1 unit.
So, the point we reach is .
