Answer:
-3
Step-by-step explanation:
Note the parts of the equation:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
In this case: y = 4x - 3
x = x
y = y
m = slope = 4
b = y-intercept = -3

Answer:
d. None of the above.
Step-by-step explanation:
<em>a. By the law of large numbers, it would again be 46%.
</em>
FALSE. This proportion (46%) is a sample statistic, that can or can not be repeated in another sample.
<em>b. By the law of large numbers, the smaller (second) survey will certainly produce a sample proportion farther from the true population proportion than the larger (first) survey.
</em>
FALSE. Smaller samples will produce wider confidence intervals for the estimation of the population proportion, but larger samples does not necessarily gives us better point estimations of the true proportion. A small sample can be closer to the true proportion than a large sample, although is less probable.
<em>c. The proportion computed from the sample of 5000 people would be more accurate because smaller samples tend to be more homogeneous than larger samples.
</em>
FALSE. There is no evidence to claim that smaller samples are more homogeneous.
<em>d. None of the above.</em> TRUE
First get into y-int form:
y=−<span><span>2x/</span>3</span>+<span><span>5/3
fill in y point:
</span></span>-3 = −<span>2/3(9) + b
b= 3
so
</span>y= −2/3(x) + 3
