Step-by-step explanation:
The . Should go after the 7
Answer:
y = 3x + 5
Step-by-step explanation:
First start at your y intercept (5) and use the rise to run ratio (rise 3, run 1) and there is a point on every single one.
1/3 wouldn't work because you rise 1 and go right 3 and that does not match any of the points
Using the two points first gives us a slope of 3
(1, 8) (2, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 8)/(2 - 1)
m = 3/1
m = 3
We also know that 8 cannot be the intercept being as it is the point at x = 1. Therefore, we know that y = 3x + 5 must be the only possible answer.
Answer:
3, 4, 7
Step-by-step explanation:
In order to solve inequalities, you want to isolate the variable.
Subtract 3 from both sides to give you (I can't put the greater than or less than or equal to with the line underneath, so just imagine that it's there)
-8 <-4r
Divide both sides by -4 to get the r by itself.
-8÷-4=2
2<r
Two is less than or equal to r, or you can word it r is greater than or equal to 2. So now you look at your options, and choose the ones that are greater than 2. 3, 4, and 7 are all greater than 2.
