Which equation represents the graphed line?

in the graph, range of the x and y axis is minus one to six by increment of one. on both axis only two, four, and six are labeled. in the graph, the line passes through the points (2, 1) and (0, 5).

a. y − 1 = −2(x − 3)
b. y − 1 = −2(x + 3)
c. y + 1 = −2(x − 3)
d. y + 1 = −2(x + 3)

Abby is collecting rainfall data. she finds that one value of the data set is a high-value outlier. which statement must be true? abby will use a different formula for calculating the standard deviation. the outlier will increase the standard deviation of the data set. the spread of the graph of the data will not change. abby will not use the mean when calculating the standard deviation.
