Question

Use the slope and y-intercept method to graph the following equations.                                                         a.)3x-4y-1=27                                                               b.)6x=2y+12

anonymous · Answer

plug in x=0 for y intercepts.
plug y=0 for x intersepts
then dray lines through the x and y intercepts...

anonymous · Answer

a)  3(0)-4y-1 = 27.......-4y = 28.......y=-7    so you have the point (0,-7)

anonymous · Answer

3x-4(0) = 28......x=28/3...... and now you have the point (28/3,0)  so you can plot the points and draw a line through them because they are linear equations...   


do the same for b.
