This only works for y=mx, not y=mx+c.
theta = tan(m)
eg y=x theta = tan(1)
.: theta = 45
You get a graph based on polar coordinates rather than Cartesian coordinates. Some shapes have simpler equations in polar coordinates: for example, a circle with centre at the origin and radius r, is simple R = r. A straight line through the origin and gradient (slope) m is tan(q) = m.
use cartesian coordinates

they both have x and y coordinates
the radius vector; and the vectorial angle the radius vector; and the vectorial angle
The graph that displays data using line segments is a line graph.
The equivalent of the x-axis
a bar graph is a graph that displays data using bars and a line graph is a graph that displays data in a line
A line graph.
Select any value for one of the variables in the graph and solve the equation to get the other variable.
It is the locus of all points whose coordinates satisfy the equation of the line.
To find the slope using a table or graph, identify two points on the line or in the table that represent (x, y) coordinates. The slope (m) can be calculated using the formula ( m = \frac{y_2 - y_1}{x_2 - x_1} ), where ( (x_1, y_1) ) and ( (x_2, y_2) ) are the coordinates of the two points. In a graph, the slope represents the steepness of the line, indicating how much y changes for a unit change in x. By examining the rise over run visually in the graph or through the differences in the table, you can determine the slope.
