Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
Substitute the coordinates of the point into the equation of the line. If the result is true, then the point is on the line.

Assume the equation is y = kx + c Put in the x and y values of your known coordinates and sove the simultaneous equations.
Yes if it is a straight line equation
The x and y coordinates

Yes if it is a straight line equation
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
True
y = 2x2 + 3x + 6 Since a > 0 (a = 2, b = 3, c = 6) the graph opens upward. The coordinates of the vertex are (-b/2a, f(-b/2a)) = (- 0.75, 4.875). The equation of the axis of symmetry is x = -0.75.

x+2y=8 The x-intercept is the value of x when y=0, therefore substitute y=0 into the equation: x+0=8 therefore, x=8 The coordinates of this point is (8,0)
