I'm pretty sure the 3rd one is right, use a calculator
Answer:
An equation in slope-intercept form of the line will be
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the points
Finding the slope between (-1,-1) and (1,0)




substituting m = 1/2 and (-1, -1) in the slope-intercept form of the line equation to determine the y-intercept



Add 1/2 to both sides


substituting m = 1/2 and b = -1/2 in the slope-intercept form of the line equation



Therefore, an equation in slope-intercept form of the line will be
What we can say with a good deal of certainty is that our sample is biased towards the higher spectrum and that the real value of the mean for our population is lower than the obtained value of our sample. If this is true, we should expect for the standard deviation to be higher than in the population.
Actually it's
y =

it's a line. so 2 points is enough
choose x so that x+4 would be divisible by 3 :)
1) x = 2, then y = (2+6) / 3 = 2 - sketch point (2,2)
2) x = 5, then y = (5+4) / 3 = 3 - sketch point (5,3)
3) line goes though those points. use ruler :)
