The Metea Valley theater program is selling tickets for their next show. They are selling adult tickets for $8 and children's tickets for $4. The ticket sales for the show totaled $560. Let x represent the number of adult tickets and y represent the number of children's tickets sold. Write an equation for the scenario in standard form.

• $8x+4y=560$

• $4x+8y=560$

• $y=-2x+140$

• $\frac{1}{8}x\ +\frac{1}{4}y\ =\ 560$

Which is the equation of the line with slope 3 and y-intercept 5.

• y = 3x + 5
• y = 5x + 3
• y = 3/5x
• y = 5/3x
