Final answer:

To graph y = 3/4x - 1/2, plot the y-intercept at y = -1/2, then use the slope of 3/4 to find another point by moving right 4 units and up 3 units from the y-intercept, and draw a straight line through both points.

Step-by-step explanation:

To graph the equation y = ¾ x - ½,

  1. Start by plotting the y-intercept at y = -½ on the vertical axis.
  2. Then use the slope, which is ¾. This means for every 4 units you move horizontally to the right (positive direction of the x-axis), you move up 3 units vertically (positive direction of the y-axis).
  3. From the y-intercept, move right 4 units and up 3 units to plot another point.
  4. Connect these two points with a straight line, which represents the graph of the equation y = ¾ x - ½.

Remember that the slope and y-intercept determine the position and orientation of the line on a graph, as outlined in Figure A1.

Answer:

in attachment

Step-by-step explanation:

An easy-ish way to graph something in slope-intercept form is to use the y-intercept and the slope because that info is given.

the y -int is when x = 0 and then y would equal -1/2. (0,-1/2)

then the slope is 3/4 which is rise over run so go three up (rise) and 4 across (run). make sure that your line has a positive slope ( / ) because the slope is positive in the equation, not negative ( \ )

You now have 2 points. Draw a line connecting the two points.
