Which coordinate grid shows Point A at (0.75, −1.50)? Coordinate grid shown from negative 2 to positive 2 on the axis and negati
Monica [59]

Answer:

The correct option is;

Coordinate grid shown from negative 2 to positive 2 on the x-axis and negative 2 to positive 2 on the y-axis in increments of 1 over 4. Only the whole numbers are labeled. A point A is shown at the intersection of 3 grid lines to the left of the y-axis and 6 grid lines above the x-axis

Step-by-step explanation:

The coordinate of the point in the question = (0.75, -1.50)

The options given are

x = -2 to 2 on the y-axis and y = -2 to 2  on the y-axis in increments of 1/4 Only the whole numbers are labelled.

Point A = 6 grid lines to the left of the y-axis and 3 grid lines above the x-axis corresponding to the point (6×(-1/4), 3×1/4) = (-1.5, 0.75)

From the above, it is seen that the point A that will correspond with the point (0.75, 1.50) will have a spacing of 3 grid lines to the left of the y-axis and 6 grid lines above the y-axis

Therefore, the correct option is Coordinate grid shown from negative 2 to positive 2 on the x-axis and negative 2 to positive 2 on the y-axis in increments of 1 over 4. Only the whole numbers are labeled. A point A is shown at the intersection of 3 grid lines to the left of the y-axis and 6 grid lines above the x-axis.

nalin [4]
The correct answer is B) y = 120000x + 420000.

We multiply 120,000 by x since that is the cost per person per day, and x is the number of days.  We add 420,000 because that is the one time cost of the round trip airfare.
