LenaWriter [7]

Answer:

√74

Step-by-step explanation:

We know the pythagorian triplet that,

A^2 + B^2 = Hypotenuse^2

Or, 5^2 + 7^2 =Hypotenuse ^2

Or, 25+49= Hypotenuse^2

Or, 74 = Hypotenuse^2

Hypotenuse= √74

PLEASE ANSWER

The approximate equation in slope intercept form is y = 3x + 2.

Solution:

Let us take (0, 2) and (1, 5) on the graph.

x_1=0, y_1=2, x_2=1, y_2=5

Equation of the line in slope-intercept form:

y = mx + b

where m is the slope of the line and b is the y-intercept of the line.

Slope of the line:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

$m=\frac{5-2}{1-0}

$m=\frac{3}{1}

m = 3

y-intercept of the line is the value of y when x = 0.

Here the value of y is 2 when x = 0. That is (0, 2) is the point of y-intercept.

Therefore b = 2.

y = 3x + 2

Hence the approximate equation in slope intercept form is y = 3x + 2.
