Question

On the grid, draw a line with a slope of 3/4 and label it l1 then sketch a second line perpendicular to the first line and label it l2. Find the y intercepts slope and y=mx+b for each

Answer 1

slope = change in y / change in x
you can start anywhere but i would just start from the origin. for the first line, count 3 units up the y-axis and then 4 units to the right of the x-axis. now, draw a point at (4,3). connect the origin to this point.

Answer 2

perpendicular means m1*m2 = -1

so the slope of the line perpendicular to 3/4 would be -4/3. graph the second line like you did for the first line, preferably at the origin but you can do it anywhere

Answer 3

the y-intercepts would be 0 if you did it at the origin. the slopes are basically given. and just plug in for y=mx+b

Answer 4

Still do not understand....
