Answer:
Without any studying, the score would be about 328
Step-by-step explanation:
The y-intercept of an equation represents the point where its graph crosses the y-axis. At this point the value of x is always equal to 0.
The y-intercept of the equation in this context would represent the Math SAT score of a student who did not do any studying, that is the number of hours spent studying, x = 0.
Substitute x = 0 in the given equation and solve for y;
y = 24.387(0) + 328.182
y = 328.182
Therefore, Without any studying, the score would be about 328
Answer:
-1
Step-by-step explanation:
rule:
y2- y1 over x2 - x1
so,
y2= 4
y1= 6
x2= 0
x1= -2
4 - 6 over 0-(-2)
= -1
21 times 100 divided by 70 =30
