Answer:
a. y = -2x + 7
Step-by-step explanation:
First, find the slope by plugging the points into the slope formula,
, which equals -2. Then use the slope and the point (7,-7) to make an equation in slope-point form. y+7=-2(x-7), finally solve for y to get y=-2x+7.
A. No, because -38 isn't a fraction.
2, No because 400 is a real number.
3. Yes because fractions, decimals, and percents are rational numbers.
