Question

Graph the equation using the slope and y-intercept

y = 1/2x - 5

Graph the equation using the slope and y-intercept

3x - 4y = 12

Answer 1

first has slope 1/2 with y intercept -5

2nd has slope = 3/4 with y intercept -3

1st has flatter slope and lower y intercept

they cross at the point (-8,-9)

Answer 2

Graph the equation using the slope and y-intercept For this one, you put a dot on (0,-5) (x,y) coordinate for the y intercept, then go right 2 (run) and up 1 (rise) for the second dot. Connect the dots for the line!

y = 1/2x - 5

Graph the equation using the slope and y-intercept for this one, you need to get it into Y=M(X) + B format first by using algebra principles. So, subtract 3x from both sides, then divide everything by -4.

1. -4y = -3x + 12
2. y = (3/4)X - 3 then use the same process as above (dot on the y intercept, 0,-3; then use rise over run for the second dot (rise 3, run 4)).

3x - 4y = 12
