Answer:
-6/5
Step-by-step explanation:
Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.
Answer:
y = 1/3x - 4/3
Step-by-step explanation:
slope is change in y over the change in x
-1 +3/ 1+5= 2/6= 1/3
y+1 = 1/3(x-1)
y + 1 = 1/3x - 1/3
y = 1/3x - 4/3
