The strategy for these is to look at what these problems are telling you.
It says the y-value, so you know that this is a y = equation.
y = what?
y = 2 more than. 4 is two more than 2, right? So saying it's more than is another way of saying "y is 2 + blah blah."
So y = 2 + what? Three times the x-value. What does that mean? 3*X = 3X.
Thus we arrive at the final answer, y = 3x + 2
2a + 8a simplified is 10a
Shared ratio is 5 : 8
Total parts
5+8 = 13
If we want to get a single part, it has to be divided by 13.
390 / 13 = 30
therefore,
5 : 8
1*5 : 1*8
30*5 : 30*8
150 : 240
Answer:
The y intercept is 6 and the slope is -3.
Please see the attached graph.
Any number that ends with a 0 or a 5 would be a multiple of 5 because as you multipy numbers by 5 you start to see a pattern in the ones place of 5,0,5,0,5,0,5,0,... And so on forever
