The parent function for lines is f(x)=x. What happens to the line if the slope is changed to 5/8?

• The line gets steeper

• The line gets less steep

• The y-intercept is translated down by 5/8 units.

• The y-intercept is translated up by 5/8 units

The parent function for lines is f(x) = x. What happens to the line if the slope is changed to 8/5?

• The line gets steeper

• The line gets less steep

• The y-intercept is translated down by 8/5 units

• The y-intercept is translated up by 8/5 units

The parent function for lines is f(x) = x. What happens to the line if you add 5 to it?

• The line gets steeper

• The line gets less steep

• The y-intercept is translated down by 5 units

• The y-intercept is translated up by 5 units

The parent function for lines is f(x) = x. What happens to the line if you subtract 7 from it?

• The line gets steeper

• The line gets less steep

• The y-intercept is translated down by 7 units

• The y-intercept is translated up by 7 units

The parent function for lines is f(x) = x. What happens to the line if you change the slope to -1?

• The line gets steeper

• The line gets less steep

• The line changes directions

• You rip the space-time continuum and form a black hole.

The Dames need to buy new face shields for their choir classes. The face shields cost $0.75 if they order a minimum of 50 of them. This is good since they only need at most 80 new face shields. What is the domain of this situation?

• $50\le x\le80$

• $\left\{50,\ 51,\ 52,\ ...,\ 78,\ 79,\ 80\right\}$

• $37.50 $\le x\le$ $60.00

• Choir and math don't mix

The amount of money the Student Council makes from a fundraiser is directly proportional to the amount of shirts they sell. If they make $275 from selling 25 shirts, how much will they make if they sell 45 shirts?

• $495

• $395

• $595

• $695
