Answer:
The slope-intercept form of the equation of this line is:
Hence, option 'c' is true.
Step-by-step explanation:
From the line equation, let us take two points
- (1, -1)
- (-1, 1)
Finding the slope between two points
From the line graph, we can determine the y-intercept by setting x=0 and checking the y-value at x=0
at x=0, y=0
Thus, (0, 0) is the y-intercept
We know that the slope-intercept form of the line equation is
y=mx+b
where
- m=slope
- b=y-intercept
As we have already determined m=-1 and y-intercept=b=0
so substituting m=-1, b=0 in the slope-intercept form of the line equation
Thus, the slope-intercept form of the equation of this line is:
Hence, option 'c' is true.
