The point slope form of the eqaution of the line that passes through (-5,-1) and (10, -7) is y+7= -2/5 (x - 10) what is the stan
stira [4]

Answer:

<h2>2x + 5y = -15</h2>

Step-by-step explanation:

The standard form of an equation of a line:

Ax+By=C

We have the equation in point-slope form:

y+7=-\dfrac{2}{5}(x-10)

Convert it to the standard form:

y+7=-\dfrac{2}{5}(x-10)     <em>multiply both sides by 5</em>

5y+35=-2(x-10)         <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

5y+35=(-2)(x)+(-2)(-10)

5y+35=-2x+20          <em>subtract 35 from both sides</em>

5y=-2x-15            <em>add 2x to both sides</em>

2x+5y=-15

Ksenya-84 [330]

Answer:

1. G IS A DEPENDENT VARIABLE

2.U IS THE INDEPENDENT VARIABLE

Step-by-step explanation:

G is a dependent variable because its values will rely on the values of U multiplied by 748. A dependent variable in most cases is isolated on one side of an equation ( mostly the left-hand side) and it value is affected by the values selected on the other side of the equation.

U is an independent variable because it stands on its own such that it does not rely on the behavior of another variable to determine its value/characteristic.Characteristic here i mean , U is freely selected without considering the behavior of other variable, thus it does not face any restrictions as compared to G.
