-BARSIC- [3]

Step-by-step explanation:

the function A, according to the tables

=> the equation : f(x) = 2x +3

the slope = 2

the function B, according to the graph

=> the equation : f(x) = 3x -2

the slope = 3

based on the value of the slope, the function B has a greater rate of change

The point A(0,3) and point B(4,19) lie on the line L.<br> Find the equation of line L
IRISSAK [1]

Answer:  The equation is   y = 4x+3

Slope = 4

y intercept = 3

========================================================

Explanation:

Let's start off by finding the slope.

A = (x_1,y_1) = (0,3) \text{ and } B = (x_2,y_2)  = (4,19)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{19 - 3}{4 - 0}\\\\m = \frac{16}{4}\\\\m = 4\\\\

The slope is 4.

The y intercept is 3 because of the point (0,3)

We go from y = mx+b to y = 4x+3

m = slope

b = y intercept

---------------

Check:

Plug in x = 0 and we should get to y = 3

y = 4x+3

y = 4(0)+3

y = 0+3

y = 3

That works out. Now try x = 4. It should lead to y = 19

y = 4x+3

y = 4(4)+3

y = 16+3

y = 19

The answer is confirmed.

If you're solving for the length of that side just use the pythagorean theorem so the hypotenuse or your missing side equals: <span>
hypotenuse = square root ( 5.5^2  + 4.83^3 )
hypotenuse = square root (30.25 + 23.3289)
</span><span>hypotenuse = square root (53.5789)
</span><span>hypotenuse = 7.32
</span>
So, the total distance is 7.32 miles.
