Question 983387: I need help to find the gradient. I need the FORMULA for finding the gradient in a manner I can understand.
4x + 5y - 9 = 0
I get 5y/4x - 9 = 0
gradient 5/4?

You can put this solution on YOUR website!
.
Slope intercept form: y=mx+b, m is the slope (gradient)
.
4x%2B5y-9=0 Put this equation in form y=mx%2Bb
.
5y=-4x%2B9
.
y=%28-4x%2B9%29%2F5
.
y=-%284%2F5%29x%2B9%2F5 m=-(4/5), b=9/5 (b is y-intercept)
.
