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

Slope: -1 intercepts: (0,1000),(1000,0)
Slope is 2.
The slope is 1.
After solving for y you will get y=1/5 x+1. The slope of this line is 1/5.
The slope is 1/3 and the y-intercept is -1.
