The graph for the equation y=2x+4 is shown below. if another equation is graphed so that the system has one solution, which equation could that be? y=2x-4 y=2(x+2) y=2(x-4) y=x+4 !

y=x+4 is the another equation so that the system has one solution.

Step-by-step explanation:

y=2x+4

find the another equation so that the system has one solution

When the slopes are equal then the lines are pependicular to each other. Then the lines never intersect.

So we should not consider the equation that has same slope

y=2x+4 , the slope of given line is 2

y=2x-4, slope =2   (same slope)

y=2(x+2)

y=2x+4  , slope =2  (same slope)

y=2(x-4)

y=2x-8, slope =2 (same slope)

y=x+4 , slope = 1 (different slope)

So y=x+4 is the another equation so that the system has one solution.

its an acute right triangle

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
