Answer:
The equation of the line is given as 2 y - x = 4.
Step-by-step explanation:
Here, the slope of the given line = 1/2
The point on the line is (x0,y0) = (6,5)
Now, by POINT SLOPE FORMULA:
The equation of line with (x0,y0) and slope m is written as:
(y - y0) = m (x-x0)
So, here the equation of line is given as
Hence the equation of the line is 2 y - x = 4.
Answer:
Step-by-step explanation:
This is asking you to write the equation in <em>slope-intercept</em> form:
where:
- m is the slope
- b is the y-intercept
- x and y are any corresponding coordinate points (x,y)
You need to find the slope of the two given points using:
Insert the values:
The slope of the given line is -1. Insert this value into the equation:
Now insert one of the given coordinate points as x and y to solve for b:
The y-intercept is 9. Insert the value:
