Question

The value of a collectable basketball card is currently $550 and increases at a rate of $50 each year. If the situation is plotted on the graph below, which of the following would be true? Select all that apply.

a. The slope of the line modeling this situation has a slope of 50.
b.The line passes through the point (3, 850)
c.The y-intercept of the line is (550, 0).
d.The line passes through point (5, 800).

Answer 1

The equation is y=550 + 50 x
so 50 would be the slope,(true)
550 + 50(3)=700,(false)
550+ (50(550) is definitely not 0,(false)
550+50(5)=550+250=800,(true)
so first one and the last one
