How do you find the equation of a line given the gradient and y-intercept?
Use the formula: @@y = mx + c@@, where m is the gradient and c is the y-intercept.
The equation is found by using the formula: @@y = c - mx@@.
You can determine the equation by calculating the slope and then using @@y = mx^2 + c@@.
The equation can be derived from the points on the line using the formula: @@y = mx + b@@.

How do you graph a linear equation?
Plot the y-intercept on the y-axis, then use the gradient to find another point, and draw a straight line through the points.
Draw a curve that connects the x-intercept and y-intercept.
Use a ruler to draw a vertical line through the y-intercept.
Plot random points on the graph and connect them with a line.
