its + 10

y=10

Step-by-step explanation:

y = 5x + 4    (if the question is asking for an equation that is)

Step-by-step explanation:

Solve for the slope using y2-y1/x2-x1

Substitute: 19 - 9/ 2 - 1

Now you get 5 as your slope

Substitute this value into y = mx+b for the y - int

Remember m is the slope and b is the y intercept

After you solve for the y - intercept you get y = 5x + 4

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
