Question

On which of the following lines does the point, (1,-13) lie?

a. y=5x-9

b. y=-2x+5

c. y=-5x+5

d. y=-3x-10

jim_thompson5910 · Answer

(1,-13) means x = 1 and y = -13

jim_thompson5910 · Answer

checking choice A


y=5x-9

-13=5(1)-9 ... replace x with 1, y with -13

-13 = 5 - 9

-13 = -4


The equation -13 = -4 is false, so (1,-13) is NOT a solution to y=5x-9

the point does NOT lie on y=5x-9

you will do the same for the other choices

anonymous · Answer

so i just input the values that it gives me into the equation for x and y? if that makes sense

jim_thompson5910 · Answer

yes and you are looking for cases when you plug in (x,y) = (1,-13) and you get a true result
