Which of the following is a correct equation for the line passing through the point (-1,4) and having slope m=-3

timurjin [86]

Answer:

y = -3x + 1

Step-by-step explanation:

Starting with the point (-1, 4) and the slope m = -3, write out the point-slope equation of a straight line: y - k = m(x - h) becomes y - 4 = -3(x + 1), or:

y = -3x - 3 + 4

y = -3x + 1 This is the same as answer choice (b).

What is the value of this expression when c=-4 and d = 10?<br> 1/4(c3+d2)

Mumz [18]

What is the value of this expression when c = -4 and d = 10 ? $\frac{1}{4}$ (c³ + d²)

<h3>Given:-</h3>

$\frac{1}{4}$ (c³ + d²) where c = -4 and d = 10

The value of the expression $\frac{1}{4}$ (c³ + d²)

<h2>Solution:-</h2>

$\frac{1}{4}$ (c³ + d²) [Given expression]

Now, putting the value of c = -4 and d = 10 , we get,

$\frac{1}{4}$ { (-4)³ + (10)² }

$\frac{1}{4}$ ( -64 + 100 )

$\frac{1}{4}$ ( 36 )

$\frac{1}{4}$ × 36
