The slope-intercept form of a straight line : y = mx + c
where m is the slope.
a)
y = 3x + 4
Slope of the straight line = 3
b)
3x + 4y = 6
4y = -3x + 6
y = (-3/4)x + (3/2)
Slope of the straight line = -3/4
where m is the slope.
a)
y = 3x + 4
Slope of the straight line = 3
b)
3x + 4y = 6
4y = -3x + 6
y = (-3/4)x + (3/2)
Slope of the straight line = -3/4
