+90 A.13x-12y=82 B.-6x=y C.7=y D. y=x2-2
Which of the following equations is not linear
Show how
+37146 A,B,C are all liear and can be put into the line form of y= mx+b
D is a quadratic...a parabola because of the exponent
+37146 A,B,C are all liear and can be put into the line form of y= mx+b
D is a quadratic...a parabola because of the exponent
+37146 Then you will have to graph it or show that it cannot be put into y= mx+b form
+37146 yes ax +by = c is just another form of y = mx + b equation for a line Good call!
+129852 Here's a way to show that x^2 - 2 is not linear
Let x = 0 ....then (0)^2 - 2 = -2
And
Let x = 2 ....then (2)^2 - 2 = 2
And
Let x = -2 ....then (-2)^2 - 2 = 2
So the points (0, -2), ( 2, 2) and (-2,2) are on the graph
Now the slope between the frist two points = 2 while the slope beween the second and third point = 0.......but....the slope beween any two points on a line is always the same
Thus, x^2 - 2 cannot be linear......
