Acoordinate grid is shown below:

part a: which point represents the origin?

part b: starting from the origin, explain how to plot the following three points accurately:

• (1, -1)
• (-1, 1.25)
• (-2, 3/4)

Find the length of cu, the triangles are similar.

Find parametric equations for the line tangent to the curve of intersection of the surfaces at the given point. surfaces: xsquared2plus+2yplus+2zequals=1212 yequals=33 point: left parenthesis 1 comma 3 comma five halves right parenthesis

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2
