whats the problem?

OpenStudy (anonymous):

Points C and D lie on graph of the equation y = 1.3x. What are the y-coordinates for each point? Point C: (3,______) Point D: (-6______)

OpenStudy (owlet):

just plug in the x-coordinates into the equation and you'll get the y-coordinate for each.

OpenStudy (owlet):

What is 1.3 x 3? What is 1.3 x -6?

OpenStudy (anonymous):

1.3 × 3 = 3.9 1.3 × (-6) = (-7.8)

OpenStudy (owlet):

you're done :) point C is (3,3.9) point D is (-6, 7.8) since both points lie on the graph, you can use the given equation y=1.3x to solve for the y-value.

exactly
