the value of a rare dime is expected to increase according to the equation, y=25x+10, wherer y is the value of the coin (in cents) after x years

a)state the slope of the line and interperate its meaning

b) state the y-intercept of the line and interperate its meaning

• math -

Equation of a Straight Line:

y = mx + c

m=slope

In this case slope=25

y-intercept of the line is value of y when x=0

In this case y=25*0+10=0+10=10

Value of a rare dime is increase 25times all years

10=Initial value of value
