Translate the point by 3 units to the left and 9 units down. (10,-10)

(7,-19)

Step-by-step explanation:

To the left means x is decreased so 10-3 and down refers to y coordinate decreasing hence - 10 - 9 that results in our answer (7,-19)

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
