"sqrt" is shorthand for "square root"

The rule to use is

sqrt(x*y) = sqrt(x)*sqrt(y)

Factor 40 into 4*10, then use the rule above to get the following

sqrt(40) = sqrt(4*10)

sqrt(40) = sqrt(4)*sqrt(10)

sqrt(40) = 2*sqrt(10)

Question 13 options: What is the slope of the line of the graph?

Elena-2011 [213]

Answer:

Step-by-step explanation:

To find the slope, pick any two points fromthe line.

(2,2) & (0,-4)

x₁ = 2 & y₁ = 2

x₂ = 0 & y₂ = - 4

$\boxed{Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}}$

$\sf =\dfrac{-4-2}{0-2}\\\\\\ =\dfrac{-6}{-2}\\\\\\=3$

Slope = 3

At y-intercept x = 0.

From the graph, y-intercept = -4

Equation of the line: y = mx + b

y = 3x - 4
