Which of the following are true statements about the line y = 2x + 3?
The gradient of the line is 2.
The line passes through the point (0,3).
The line is parallel to y = 2x - 1.
The y-intercept is -3.
解释
The coefficient of x is the gradient and the constant is the y-intercept. Lines with the same gradient are parallel
