Question
Identify the equation of the line with a slope of –3.
- y = 3x+ 4
- y = 3x– 4
- y = –3x+ 4
- y = –3x– 4
Hint:
we know intercept form of line equation
y = mx + c
where m = slope
and c = intercept ( where the line cut the axis)
The correct answer is: y = –3x+ 4
The equation is y = –3x + 4.
we know the equation of the line which is intercept at point c
The x-intercept is the point where the slope of a line crosses the x-axis and the y-intercept is the point where the slope of a line crosses the y-axis
