Hmmm it would be kind of hard to graph as it will be a curved line but the middle of the line would be at (2,-7). Not (-2,-7).
And it will be curving upwards, meaning it will start by going down and end by going up.
Hope this helps some.
Answer:
3n + 7 + n and 4n + 7
Step-by-step explanation:
Gradient = 7-(-1)/4-3
= 8
when x = 3, y = -1,
y = 8x + c
-1 = 8(3) + c
c = -1 - 24
= -25
the equation of the line is y = 8x - 25.
There are no solutions to the equation.
Subtracting 3x from both sides gets you -12 = 1 which is never true therefore for any value of x you choose the equations will never equal each other
