Write the standard form of the equation of the line through the given point with the given slope. Through (-2,5), slope =-4
AleksandrR [38]

Answer:

\huge\boxed{4x+y=-3}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>(x₁, y₁)</em><em> - point on a line</em>

<em>m</em><em> - slope</em>

<em />

We have

m=-4,\ (-2,\ 5)\to x_1=-2,\ y_1=5

Substitute:

y-5=-4(x-(-2))\\\\y-5=-4(x+2)

Convert to the standard form

Ax+By=C

y-5=-4(x+2)                <em> use the distributive property</em>

y-5=(-4)(x)+(-4)(2)

y-5=-4x-8               <em>add 5 to both sides</em>

y-5+5=-4x-8+5

y=-4x-3               <em>add 4x to both sides</em>

4x+y=-4x+4x-3\\\\4x+y=-3

Evaluate the numerical expression 4(8 - 2) = (-3) + 7
Fofino [41]

Answer:

4 ( 8 - 2 ) = (-3) + 7 -> this is a false statement

Step-by-step explanation:

4 ( 8 - 2 ) = ( -3 ) + 7

Simplify the parenthesis

4 ( 6 ) = (-3) + 7

Multiply;

24 = (-3) + 7

Add, remember, adding a negative number and a positive number is the same as subtracting the negative number from the positive number,

24 = 4

This statement is not true.
