Ethan, Grace, and Michael are having a friendly competition to see who can come up with the best equation to represent the growth of a farmer's crops. Which equation do you think best represents this?

• y = 2x + 3

• y = 3x - 2

• y = 4x + 3

• y = 35x

Answer explanation

The best equation to represent the growth of the farmer's crops is y = 4x + 3. This equation suggests a linear relationship between the growth of the crops and the variable x, with a slope of 4 and a y-intercept of 3. This means that the growth rate is consistent and increases by 4 units for every unit increase in x, with an initial growth of 3 units.

James, Ethan, and Priya are on a hiking adventure! They start at point A (-2, -2) and move to point B (3, 4) on a coordinate plane. Can you help them figure out the slope of the path they took?

Answer explanation

To find the slope of the path between points A(-2, -2) and B(3, 4), we can use the formula: slope = (y2 - y1) / (x2 - x1). Plugging in the coordinates, we get (4 - (-2)) / (3 - (-2)) = 6 / 5. Therefore, the correct answer is \(rac{6}{5}\).
