In the equation y = 3x, what is the y intercept? What are the coordinates (x, y) of the intercept?

y intercept (0|0)

x intercept (0|0)

Step-by-step explanation:

Y intercept means x=0

y=3*0

y=0. So the point is (0|0)

X intercept means y=0

0=3x

X=0. So the point is also (0|0)

question:

could we have options?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
