Examples For Section 2.3

Problem Number 25

Write an equation of the line passing through the points ( 1 , 2 ) and ( 5 , 10 ) in point-slope form and in slope-intercept form.

Problem Number 35

Write an equation of the line passing through the point ( 2 , 4 ) with an x-intercept value of -2 in point-slope form and in slope-intercept form.

Problem Number 43

Give the slope and y-intercept of the line whose equation is given.

In the picture the purple circle represents the y-intercept point and the blue circle represents the point found by starting from the y-intercept point and using the slope of 3/4 to go up 3 and over 4 to find another point on the graph.

Problem Number 61

Give the slope and y-intercept of the line whose equation is given and use the slope and y-intercept found to graph the linear function.
