Answer:

b)11

since 11^2 is 11*11 = 12

and when you take the square root of 121

we get 11

(in b- √11^2) , it cancels out the square

square root cancels square since they perform opposite functions

Determine the slope and the y-intercept of the line represented by the equation y= -7/3×+3 slope: 7/9 ;y-intercept: 3 slope: 9/7

Mademuasel [1]

Answer:

$slope ⟹ \: - \frac{7}{9} \\ y \: intercept⟹ \: 3$

Step-by-step explanation:

The standard form of this equation is

$y = mx + c \\$

m stands for the gradient or the slope, and c represents the y-intercept

$y = mx + c \\ y = - \frac{7}{9} x + 3 \\ m = - \frac{7}{9} \: \\ and \: \\ \: y \: intercept \: = 3$
