1.
|
The slope of the line y = 4 + 3x is 4.
|
|
|
2.
|
The slope of the line x+y = -2 is -1.
|
|
|
3.
|
If we rearrange 2 x + 3 y = x + 2 into the standard form
y = mx+ c then m is  and c is 2
|
|
|
4.
|
If we put the quadratic expression 2x + 1 + 3x2 –
4x into the standard form ax2+bx+c then b is -2.
|
|
|
5.
|

|
|
|
6.
|

|
|
7.
|
y = 1-2x2 has a single root.

|
9.
|
A cubic function must have at least one root.
|
|
