find the gradient and y ntercept of the line with equation: y = 9  4x
choose the one option which gives the gradient and one option which gives the y intercept from the list below.
9, 4, 9/4, 4/9, 4/9, 9/4, 4, 9
can any1 help me this is very confusing.
The gradient is commonly called the slope, the coefficent of x.
y= 4x + 9
In this format, one can see the gradient is 4, and the y intercept (when x is zero) is 9
