Write an equation for the line that passes through (-1,4) with a slope of -10

Mathematics
1 answer:
Maurinko [17]3 years ago
4 0

Answer:

y = - 10x - 6

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 slope m = - 10, hence

y = - 10x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = 10 + c ⇒ c = 4 - 10 = - 6

y = - 10x - 6 ← equation of line

What is the value of this expression when c = -4 and d = 10?
lianna [129]

The complete question is

"What is the value of this expression when c= -4 and d= 10?

1/4 (c^3+d²)

A.2

B.9

C.21

D.41"

The value of this expression when c = -4 and d = 10 will be option B 9.

<h3>What is a simplification of an expression?</h3>

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

The given expression is

1/4 (c^3+d^2)\\\\1/4 ((-4)^3+(10)^2)\\\\1/4 ( -64 + 100)\\\\1/4 (36)\\\\9

Hence, the value of this expression when c = -4 and d = 10 will be option B 9.

Suppose y varies directly as x , and y=−319 when x = 29. Based on this information, write a direct variation equation that relat
Len [333]

Answer:

y =  - 11x

Step-by-step explanation:

If y varies directly as x, then we can write the relation

y = kx

where k is the constant of proportionality.

We substitute y=-319 when x=29.

- 319 = 29k

This implies that:

k =  \frac{ - 319}{29}

k =  - 11

The variation equation now becomes

y =  - 11x
