That expression is the expected value of your winnings, or "the average amount you will win (or lose) per game in the long run".
Answer:
y = −3x+7
Step-by-step explanation:
m = slope
slope = change in y / change in x
slope = ▲y/▲x
slope = -3 / 1
slope = -3
y-intersect = (0,7)
The slope-intercept form of linear equation:-
y = mx + b
where:
m = the slope
b = y-intersect
*we plot the information we have get in the formula
y = mx + b
y = -3x + 7
*and this is the equation of the graph
2800 x 0.07 = 196
2800 + 196 = 2996
Total paid = $2996
