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
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
