You observe that the line shown below passes through the point (0,4 )and has a slope of 1/2. You choose (x,y) as an arbitrary point on the line other than (0,4) and use the fact that the slope of a line is constant to write which equation?


Answer:
[tex]y= \frac{1}{2}x + 4[/tex]
Step-by-step explanation:
The given line passes through the point (0,4) and has a slope of ½.
If we choose an arbitrary point (x,y) on the line, the slope of this line is given by:
[tex] \frac{y - 4}{x - 0} [/tex]
Since the slope of a straight line is constant, the above expression for the slope must be equal to ½.
This implies that:
[tex] \frac{y - 4}{x - 0} = \frac{1}{2} [/tex]
We simplify to get:
[tex] \frac{y - 4}{x} = \frac{1}{2} [/tex]
This implies that:
[tex]y - 4 = \frac{1}{2} x[/tex]
The equation of this line is therefore:
[tex]y = \frac{1}{2}x + 4[/tex]
