Answer correclty

question 1:
what is the first step to writing an equation in slope-intercept form using the given points: (-1, 0), (-2, -2).

a) use point-slope form

b) substitute -1 for x and 0 for y in y = mx + b

c) find the slope using the slope formula
y2 - y1
x2 - x1

d) find the slope using the slope formula y = mx + b

question 2:
the events x and y have a correlation coefficient of r= 0.02. what is the relationship between x and y?

a) the events have a strong negative linear correlation.

b) the events have a strong positive linear correlation.

c) the events have a weak negative linear correlation.

d) there is little or no linear correlation.

question 3:
camille asked five of her friends how long they studied for the last math test and what grade they received. she found a linear regression equation for the data to be y = 9.6x + 65.8, with x representing hours.

what does the 9.6 and the 65.8 mean in the context of this equation?

a) 9.6 = the lowest score you can get;
65.8 = the highest score you can get

b) 9.6 = the number of points you would increase each hour of studying;
65.8 = your score if you studied 0 hours

c) 9.6 = the number of points you would increase each hour of studying;
65.8 = the highest score you can get

d) 9.6 = the number of hours you studied;
65.8 = your score if you studied 0 hours

question 4:
which ordered pair would not appear as a solution for the linear equation y = −x + 3?

a) (0, 3)

b) (-1, 4)

c) (3, -2)

d) (-7, 10)
