Answer:
51
Step-by-step explanation:
To find the slope use the Rise over Run rule
It rises 2 units and runs 1 unit, so your slope is
2 or 2/1
To find the y-intercept just find where the line crosses the y-axis
it crosses at the -4 mark
Your slope is 2 and y-intercept is -4

Answer:
Consider x^ {2}-4x+3. Factor the expression by grouping. First, the expression needs to be rewritten as x^ {2}+ax+bx+3. To find a and b, set up a system to be solved. a=-3 b=-1. Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. The only such pair is the system so
Step-by-step explanation:
Answer:
Step-by-step explanation:
Here is how to get 9:
3x = 4(x - 2.25)
Solve 4(x - 2.25)
3x = 4x - 9
Move the variable to the left side and change it's sign
3x - 4x = -9
Combine like terms
-x = -9
change the signs
x = 9
There ya go! I hope this isn't too confusing!
