Chapter 1.1, Problem 46E

An accounting firm determines that the value V (in dollars) of a copier t years after its purchase is given by V=300t+1500. Interpret the y - intercept and slope of this line.

Find an equation of a line parallel to the line y=3x+1 that contains the point (4,2) . Write the equation in slopeintercept form.

Find an equation of a line perpendicular to the line y=12x3 that contains the point (6,4) .

Find the equation of the line perpendicular to the line y=3 and passing through the midpoint of the segment joining 2, 4 and -6, 10.

Find the x-intercept and y-intercept on the line shown. .

Use the slope formula to find the slope of the line through the pair of points: (3,4) and (2,1) .

What is true of the appearance of graphs thatre?ect a direct variation between two variables?

Is the point (3,0) on the x-axis or y-axis? How do you know?
