Answer:
I believe that it would be y=$0,25x+$5
Step-by-step explanation:
The initial cost to get into the arcade is $5 so that would be the y-intercept (b) in a slope equation (y=mx+b). Since each game costs $0,25, then that would be the slope (m) and x would be the number of games she played. y would equal the total amount of money spent. So if she played 10 games, substitute 10 for x and multiply by 0,25 and take the answer and add 5 to get the total amount.
Answer:
x=3,2i,-2i
Step-by-step explanation:
To find the slope and y-intercept, you can convert the linear equation into the form y = mx + b, where m is the slope and b is the intercept.
To do so, just simplify for y.



So, the y-intercept is (0, 28) and the slope is 4.5.
