Find the slope and the yintercept of the equation 7x 9y 64
Find the slope and the y-intercept of the equation.
7x + 9y = 64
Solution
7x + 9y = 64
standard equation of line in slope intercept form is
y = mx + b
where, m is slope and b is y intercept
so writing the equation in slope intercept form
7x + 9y = 64
subtract 7x from both sides
9y = -7x + 64
divide both sides 9
y = - ( 7/9 ) x + 64 / 9
therefore, slope = -7/9
y intercept = 64/9
