Answer:

y = - 4x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4, thus

y = - 4x + c ← is the partial equation

To find c substitute (- 1, 6) into the partial equation

6 = 4 + c ⇒ c = 6 - 4 = 2

y = - 4x + 2 ← equation of line

Bond [772]

Answer:

$\therefore10m+\frac{n^2}4 =54$

Step-by-step explanation:

Variables : The value of a quantity which can be changed.

Monomial : Monomial contains only one term.

Example 3x, 4,6y² etc.

Binomial: Binomial contains two terms.

Example 3+4y, 20+7z etc

Trinomial: Trinomial contains 3 terms.

Example 5x-2y+5, 7z-3y+4x etc.

Given that,

$10m+\frac{n^2}4$ [ It is a binomial.]

Putting m =5 and n=4

$= (10\times 5)+\frac{4^2}4$

$=50+\frac{4\times4}{4}$

$=50+4$

=54

$\therefore10m+\frac{n^2}4 =54$

PLZZ HELP!!!!!!

UNO [17]

Answer:

The answer is $x = - 30$ , by using the Subtraction Property of Equality.

Step-by-step explanation:

Solve for $x$ :

$-2 = x + 28$

Turn the equation over:

$x + 28 = -2$

-Subtract both sides by $28$ by using Subtraction Property of Equality:

$x + 28 - 28 = -2 - 28$

$x = -30$

So, the final answer is $x = -30$ .
