Factorising, we have,
9x2+ 30x + 25 = (3x + 5)2;thus,
when y = 0, x = -1⅔.
This tells us that the sole x-intercept of this function is at the vertex, (0, 1⅔).
y=x+1 there for answer is 2
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
+ 1/8
Upwards.
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
It is a straight line with gradient -A/B and intercept C/B.
y=x+1 there for answer is 2
-2x plus 3y equals 1
y = -0.5x plus or minus any number

The lines are parallel.
A graph that has 1 parabolla that has a minimum and 1 positive line.
down
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
Same way you graph y = -4x - 0.5
the graph is moved down 6 units
