Find equation in slope-intercept form. Slope =-1 ,ordered pair:(4,-3)

Mathematics
1 answer:
Shalnov [3]3 years ago
7 0

Answer:

y = - x + 1

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 = - 1, thus

y = - x + c ← is the partial equation

To find c substitute ( 4, - 3) into the partial equation

- 3 = - 4 + c ⇒ c = - 3 + 4 = 1

y = - x + 1 ← equation of line

GalinKa [24]

Answer:

24

-560

Step-by-step explanation:

(1) (-2) * 3 * (-4)

A negative time a negative is a positive

2*3*4 = 24

(iv) 8 x 7*(-10)

This result will be negative since there are positive times negative

8*7 =56* 10 = 560

8*7* (-10) = -560

X2 + 8x + 19 = 0 What is the equivilent that results from completing the square?
IrinaVladis [17]

Answer:

(x+4)^2+3=0

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: ax^2+bx+c

So order to complete the square, you need to take the b term out of the equation, divide it by two, and then square it

In this case, the b term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

x^2+8x+16+19=16

Now you can simplify the LHS

(x+4)^2 +19=16

Now you subtract 16 from both sides

(x+4)^2+3=0

So this is as far as you can go since you cannot take the square root of a negative number
