Gradient of given line is 2.1/5 = 21/50
So gradient (slope) of perpendicular is -50/21 = -2.381 (to 3 dp)
There is no y-intercept or slope for this given equation, because its graph is a vertical line perpendicular to the x-axis.
Then that part of the graph is below the x-axis.
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.
There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis
Same way you graph y = -4x - 0.5
answer is 1
There is no y-intercept or slope for this given equation, because its graph is a vertical line perpendicular to the x-axis.
Any graph with the slope of -1/2
6
35
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
Then that part of the graph is below the x-axis.
+ 1/8
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
2a = b Is an example of an equation with linear dependence between the variable a and b (b is twice a)If you know any a you can find the bIf you graph this equation with a on one axis and b on the other (perpendicular) you will get a straight line
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.
