Step-by-step explanation:
I am only in middle school, this question is for college. sorry
Answer: First option.
Step-by-step explanation:
You need to remember that to factorize the given expression
, you need to choose two numbers that when you add them you get "10" and when you multiply them you get "21".
These number are:
7 and 3
Because:

Therefore, you get that the factorization of the expression
is the following:

You can observe that this factorization matches with the first option.
Answer:
<u>The graph of y>-3x+1 through the points </u><u>(0,1)</u><u> and </u><u>(1,-2)</u>
Step-by-step explanation:
y=3x+1 is in the slope intercept form
y=mx+b
m = the slope in this case 3
b = the y intercept in this case 1.
Think of b the y intercept as the beginning this is where to start the graph.
So start with (0,1) the y intercept and make the first point at (0,1)
Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line
So in this case go up three on the y axis and over 1 on the x axis.
make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)
Now connect the points. creating the line
