Yesterday, selma read 75 pages of her book. if she reads at a pace of 2 pages per minute today, it means every minute,while reading, 2 pages will be added to her total number.using the general form of a linear equation: y = mx + bhere,m is the rate of change or simply the slope, which is 2 pages/minute. and y-intercept will be the number pages she has already read.so,y = 2x + 75now using this equation, we have to see which table satisfies the equation.taking 1 or 2 values from each table, we will get; table 1: x = -16 and y = 43substituting the values,43 = 2(-16) + 7543 = -32 + 7543 = 43again,x = 6 and y = 87substituting the values,87 = 2(6) + 7587 = 12 + 7587 = 87.again,x = 27 and y = 129substituting the values,129 = 2(27) + 75129 = 54 + 75129 = 129this satisfies the equation.therefore, the best answer is the table option 1.

yesterday, selma read 75 pages of her book. if she reads at a pace of 2 pages per minute today, it means every minute,while reading, 2 pages will be added to her total number.

using the general form of a linear equation:

y = mx + b

here,

m is the rate of change or simply the slope, which is 2 pages/minute. and y-intercept will be the number pages she has already read.

so,

y = 2x + 75

now using this equation, we have to see which table satisfies the equation.

taking 1 or 2 values from each table, we will get;

table 1:

x = -16 and y = 43

substituting the values,

43 = 2(-16) + 75

43 = -32 + 75

43 = 43

again,

x = 6 and y = 87

substituting the values,

87 = 2(6) + 75

87 = 12 + 75

87 = 87.

again,

x = 27 and y = 129

substituting the values,

129 = 2(27) + 75

129 = 54 + 75

129 = 129

this satisfies the equation.

therefore, the best answer is the table option 1.
