Answer: 9 / 70Explanation:Find attached the image with the grid that accompanies this question.
1) The
grid has area 7 × 10 units²
⇒
area = 70 units²2) The figure inside the grid is a
triangle with base 6 units and height 3 units.
⇒
area of the triangle = base × height / 2 = 6 units × 3 units / 2 =
9 units²3)
Probability = area of the triangle / area of the grid⇒ Probability = 9 units² / 70 units² =
9 /70
Negative 2 so you would write. -2 just like that
Y=.75x+12 since 12 is the y-intercept and .75 is the slope
