Graph the linear equation. identify the x intercept using desmos as graph calculator to check your answer 18. y = 1/5x + 3
19. y = 6x - 7
20. y = -8/3x + 9
21. y = -1.4x - 1
22. y + 9 = -3x
23. y = 4 - 3/5x

I Will appreciate the help.
this due today so please help me finish it.
( it very important)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

if x = 1, then the answer is 3.5

its an acute right triangle
