In the xy-plane, the points (a, 0) and (0, b)

In the xy-plane, the points (a, 0) and (0, b) are on the line whose equation is y = (1/2)(x) + 10. Quantity A: a Quantity B: b Quantity A is greater., Quantity B is greater., The two quantities are equal., The relationship cannot be determined from the information given.

3 Explanations


That's right :) We have a positive slope and a positive y intercept.

(a,0) is really just where the line crosses the x axis. And we know this is to the left side of the XY plane (to the left of the y axis), so "a" must be negative.

(0,b) is where the line crosses the y axis. But we know this value is 10, which is positive.

Slope =1/2 so positive slope .
Y intercept is 10
A is thus neg if we draw a xy plane therefore
