Write an equation in point-slope for, for the line through the given spot (4, -6); m = 3/5
oee [108]

The point-slope form:

y-y_1=m(x-x_1)

We have the point (4, -6) and the slope m = 3/5. Substitute:

y-(-6)=\dfrac{3}{5}(x-4)\\\\\boxed{y+6=\dfrac{3}{5}(x-4)}

Y-x=15 y-x=5 using elimination
Galina-37 [17]

Answer:

No solution

Step-by-step explanation:

To eliminate is to get rid of one of the variables.

You can choose to either add each term in the equations or subtract each term in the equation.

For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.

Try adding them.

.     y - x = 15

<u>+    y - x = 5</u>

2y - 2x = 20   No variables were eliminated.

Try subtracting.

.     y - x = 15

<u>-     y - x = 5</u>

0y - 0x  = 10   All variables were eliminated.

.         0 = 10     This is false.

This system of equations cannot be solved.

Graphically, these two lines would have the same slope and are parallel. The solution to a system is same as the point of intersection. Parallel lines never meet, never intersect, therefore there is no solution.

Find the distance between (2,7) and (-6,-2)
stepladder [879]

Answer: \sqrt{145}

Step-by-step explanation:

1. use the distance formula!

distance = \sqrt{(x_{2} - x_{1})^{2}  +{(y_{2} - y_{1})}^2

2. then using the distance formula with (2, 7) and (-6, -2) you get...

distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}

distance= \sqrt{8^2 +9^2}

distance=  \sqrt{64 +81}

distance= \sqrt{145}

\sqrt{145} is the simplest radical form
