The second graph because 2x5=10, 4x5=20, 6x5=30!
<h3>
Answer: Second graph</h3>
Why? Because we draw a dashed line through x = -1/2 = -0.5 on the horizontal number line (aka x axis). Then we shade to the right of this dashed line. The shaded region represents all points that make the inequality true. For example, the point (0,0) is in the shaded region. It has an x coordinate of x = 0 which is larger than -1/2
Side note: the dashed line says "points on this boundary do not count as solutions". So any point with an x coordinate of -1/2 does not count.
Answer:
Trend lines are lines used to approximate the general shape of a scatter plot. A positive trend line tells us the scatter plot has a positive correlation. A negative trend line tells us the scatter plot has a negative correlation.
2×2=4
1×4=4
and I guess you can also flip 1×4 around and have 4×1 as your third one?
Yes. x would be 75. For the second part yes. she would have to get 100 % on her last test.
