The answer is 1/8!
Step-by-step explanation:
I took the test and got this question correct! Good luck everyone, you'll do great! Especially with this correct answer =)
To determine the scale factor of the dilation, we determine the distances between the endpoints of the two lines through the equation,

Step-by-step explanation:
Answer: The slope is -32
Explanation:
Start with the slope formula:
m= (y2 - y1) / (x2 - x1)
Substitute point values in the formula
m = (-25 - 7) / (85 - 84)
Simplify each side of the equation
m= (-25 - 7) / (85 - 84) = -32/1
Solve for slope (m)
m= -32
Y=5x+3. because your y axis is moved
1 and 5, 3 and 7, and 4 and 8
3x-13=305
