The answer would be C.. It can also be written as a:b or a to b
Answer:
Hundreds
Step-by-step explanation:
I'm assuming you mean place value
Y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = -3x (which is the slope you are given) + b, and replace x and y with values given, which are (1,4)
y = -3x + b
4 = -3(1) + b
4 = -3 + b
7 = b
Then replace b in the first equation to get the answer
y = -3x + 7
Answer:
4
Step-by-step explanation:
To find the scale factor divide the new length by the original.
10/ 2.5 = 4
The scale factor is 4.
