B. Y= 2/5x +1 remember rise over run so you can figure out your first fraction and then look for where the line hits the y-axis so you know you y intercept
Answer:
A=1.75
Step-by-step explanation:
"horizonally" and "x-coordinate" are very much related.
If you start with a point and move the point horiz., the x-coordinate will change accordingly. If the original point were (2,3) and the point is translated 3 units to the right, then the new x-coord. would be 2+3, or 5: (5,3).
The slope is the line that describes the direction and steepness of a line.
Answer:
Factoring by grouping effectively breaks down the polynomial into easy-to-solve smaller polynomials. The goal is to isolate each term in a separate group and then add them together to finally get the original polynomial.
Step-by-step explanation:
The first thing we'll do is look for two numbers that multiply together to give -9. These will be our "groupings". Once we find these, we'll start grouping other terms in an alternating fashion until we can't break any more of the terms apart.
We find 2 and 3 which when multiplied give -6, so these are our groupings for this problem:
2x3(-9)=-18 + 5x(-9)=-45 + 4
