If the X and Y-intercepts of line L are 2 and 3 respectively then find the slope of line L.

In the figure, some points on lines l, t and n are given. Find the slopes of those lines. Observe the type of angles made by these lines with the positive direction of X-axis and try to find a relation between the type of angle and sign of the slope.

Find the slope of line l which is parallel to X -axis . Also , find the slope of line n which is parallel to Y-axis .

Find the X-intercept of the line whocse slope is 3 and which makes intercept 4 on the Y-axis.

Find the Y-intercept of the line whose slope is 4 and which has X-intercept 5.

Solve the following:If the angle between two lines in 45^o and the slope of one of the line is 1/2 ,find the slope of the other line.
