Answer 3

Generally linear equations can be written in the form y=mx+c
Where m is the gradient and c is the y-intercept
The gradient can be found from \[(y _{1}-y _{2})/(x _{1}-x _{2})=m\]
If you know two coordinates then c can be found by subbing in one pair of coordinates into y=mx+c

Answer 4

Eliza is very correct, but you may be more familiar with the term slope. Gradient is just a certain calculus term that in this case refers to the slope of the line, m in the equation y=mx+b.
Otherwise, follow Eliza. To find the slope, use his equation for the gradient if you are given two points. If you have a graph, you can use (rise)/(run), and count how many points upwards divided by how many points across to find the slope. To get the y-intercept, just find the place where the line intersects the y-axis. Plug those numbers into y=mx+b and you should have your answer.
