Option (4)

Step-by-step explanation:

Let the input output values of the table are represented by the equation,

y = mx + b

Here m = rate

b = y-intercept

Since, at x = 0, y = -1 [Point given in the table]

y-intercept 'b' = 0

Rate = $\frac{y_2-y_1}{x_2-x_1}$

Where (x_1,y_1) and (x_2,y_2) are two points given in the table.

If the points are (-2, -5) and (-1, -3),

Substitute the values in the formula,

Rate = $\frac{(-5)-(-3)}{(-2)-(-1)}$

= $\frac{-5+3}{-2+1}$

= 2

Therefore, Option (4) will be the answer.

1) 5/7 (2) 12/8 or 1.5 (3) 1/6

Step-by-step explanation:

$\frac{2}{7}+\frac{3}{7}\\\mathrm{Apply\:rule}\:\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\=\frac{2+3}{7}\\=\frac{5}{7}\\2)\\\\$

$\frac{5}{8}+\frac{7}{8}\\\\$

$=\frac{5+7}{8}\\=\frac{12}{8}\\or \\1.5$

$\frac{2}{3}-\frac{1}{2}\\\mathrm{Least\:Common\:Multiplier\:of\:}3,\:2:\quad 6\\=\frac{4}{6}-\frac{3}{6}\\=\frac{4-3}{6}\\=\frac{1}{6}$
