Answer:
Step-by-step explanation:
Do you know the first step
To simplify this expression you would factor out the greatest common factor which is y^2.
9y^2 - 11xy^2 -----> Factor out y^2
y^2(9 - 11x) ----> This should be as far as you can go, meaning this is your final answer!
Hope this helps!
Y=mx+b m=slope
so the equation that you want to find will have 1 for x and 4 for y and will have the same slope (-4) as y=-4x-5 but different 'b' value so
y=-4x
if we subsitute 1 for x we get
y=-4
which is not correct we want
x=1 and y=4 so
y=-4+8=4 so
y=-4x+8 is the equation
