In the equation:

y = mx + c

m is the gradient (or slope) and c is the point at which the line crosses the y-axis.

Therefore, we are looking to determine m.

Your equation is:

4x + 7y = 28

Let's rearrange this as follows:

7y = -4x + 28

Now divide by 7 throughout:

y = (-4/7)x + 4

Therefore, m = -4/7, or -0.5714
