slope
y-intercept
Explanation:
The equation of a line in the form
#color(red)(|bar(ul(color(white)(a/a)color(black)( y = mx + c )color(white)(a/a)|)))#
where m represents the slope and c, the y-intercept.
is useful in that we can extract slope and y-intercept 'easily'Rearranging 4x - 6y + 3 = 0 , into this form will allow us to do that.
move 4x and +3 to the right side ,remembering to change their signs.
hence: -6y = -4x-3 , and dividing both sides by -6
# (cancel(-6) y)/cancel(-6) = (-4)/(-6) x + (-3)/(-6) #
#rArr y = 2/3 x + 1/2 #
#rArr m = 2/3 " and " c = 1/2 #
graph{2/3x+1/2 [-10, 10, -5, 5]}
