EXPLANATION
First, we need to draw the graph by plotting the given points as shown as follows:
As we can see, this is a line. We can conclude this because we draw a line that match the given points.
In order to obtain the equation of this line, we need to compute the slope.The y-intercept is not necessary to compute because it's given ---> y-intercept = (0,6)
The equation of a line is as follows:
y = mx + b where m is the slope and b the y-intercept
The equation of the slope is:
![\text{Slope=}(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/college/y1d1i9zz27jw5h93ntdgud9pp9cfyczp9o.png)
Taking either ordered pair allow us to compute its value, as for instance, (x_1,y_1)=(1,10) and (x_2,y_2)=(2,14).
Replacing terms:
![\text{Slope}=(14-10)/(2-1)=(4)/(1)=4](https://img.qammunity.org/2023/formulas/mathematics/college/yg6ha1ebbs2k0bt2cxuwvh0o3ihic7jnj7.png)
Hence, as the slopeis m=4 and the y-intercept is b=6 the equation of the line is as follows:
y = 4x + 6
Additionally, the unknown value is (11,50) as obtained on the graph.
