119 ÷ 9 = 13 2/9
702 ÷ 9 = 78
432 ÷ 9 = 48
641 ÷ 9 = 71 2/9
372 ÷ 9 = 41 3/9 ⇒ 41 1/3
702 and 432 are divisible by 9. The rest are not.
For question number 1, the correct answer would be the x coordinate would be the same, or will not change.
For question number 2, the correct answer would be (-4,-7)
For question number 3, the correct answer would be <span>A'(5, -3), B'(2, -1), C'(-2, -4)
For question number 4, the correct answer would be </span><span>R'(-3, 2), S'(-5, -2), T'(-6, 0)

Remember that the y-intercept is where the function has a value of
and the x-intercept is where the function has a value of
. Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.
<u>x-intercept</u>
Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for
.



The x-value of the x-intercept is
and the y-value is 0, meaning that the x-intercept has coordinates
.
<u>y-intercept</u>
Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for
:


The y-value of the y-intercept is -3, meaning that the y-intercept of the function is
.
