What are coordinates for -4x plus 9y equals 0?
-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
What are the coordinates of the x-intercept of the equation 2y equals 4x plus 3?
2y = 4x + 3At the x-intercept, y=0.0 = 4x + 34x = -3x = -3/4The coordinates of the point are (-3/4 , 0)
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
How many roots 3x2 plus 4x plus 8 have?
No real roots.

-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
How many roots does y equals x2 - 4x plus 6 have?
No real roots. Imaginary roots as this function does not intersect the X axis.
What are the coordinates of the x-intercept of the equation 2y equals 4x plus 3?
2y = 4x + 3At the x-intercept, y=0.0 = 4x + 34x = -3x = -3/4The coordinates of the point are (-3/4 , 0)
How many roots does y equals x2-4x plus 4 have?
y = x2-4x+4 Since the highest degree term is 2, it must have 2 roots
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
