x-intercept happens when y=0
0=x2+6x-7
0=(x - 1)(x + 7)
x-intercepts are x=1 and -7
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
slope
At -7.
It is y = x + 4
The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has been changed somewhat. Which of the following could be the equation of F(x)?
-2x plus 3y equals 1
The slope of the line that represents the graph of that equation is 15.
35
x=1 and x=-7 are.
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
Since no points were given, for any point (x,y), plug the x and y values of the point into the equation. If you get a contradiction, ie 5=3 or something similar, then the point does not lie on the graph.
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
The equation 0 equals 0 is an identity and contributes absolutely nothing to the part of the graph that you should shade or not. The tautological statement can be ignored.
A linear equation ?
The slope of the graph of that equation is -1.
