Answer:
Step-by-step explanation:
You have a 30-60-90 triangle. The sides of a 30-60-90 are in the ratio 1:√3:2.
The side opposite the 30° angle is 5, so the side opposite the 60° angle is 5√3, and the side opposite the 90° angle is 5×2 = 10.
x = 5√3
y = 10
In each table, the x-values differ by 6. A linear function will also have a constant difference of y-values. Only the 4th table has that.
(x, y) = (-6, -3), (0, 2), (6, 7), (12, 12)
_____
An increase in x by 6 produces an increase in y by 5. The slope of this linear function is 5/6. In slope-intercept form, the equation is y = (5/6)x + 2.
