X-coordinate: -.50
Y-coordinate: -.55
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table
m =
= - 
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
y = -
x + 28 ← equation of line → D
The answer is 1/4, there are 4 options and the baseball cards are one selection.
30 * 0.30 = 9
30 + 9 = 39
30 increased by 30% = 39
