It looks like this came from some multiple choice question, where you're given several choices. Take each choice and substitute the x and y coordinates into the equation. So for example the point is (0,3), then substitute in and get 2*0 + 3 which equals 3 and satisfies the equation, so the point is on the graph. If the point is (1,1) then 2*1 + 1 = 3 which satisfies the equation, so that point is also on the line.
You want to find one where the left side does not equal 3, then that point is not on the graph of the line.
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
x + y = 5y = -x + 5The graph is a straight line, with [ slope = -1 ], passing through the point [ y = 5 ] on the y-axis.
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
If a = b then it is a circle; otherwise it is an ellipse.
The graph of the equation is a straight line. 'm' is its slope. 'b' is its y-intercept
(a) y = -3x + 1
It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.
-2x plus 3y equals 1
y = -0.5x plus or minus any number
A linear equation ?
Same way you graph y = -4x - 0.5
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
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 starting point on the y-axis changes from -2 to 6.
answer is 1
y=6
That is the standard equation to graph a line.
