Write an equation in slope intercept form for the line with slope negative three fourths and y intercept of negative one

Stells [14]

The slope intercept form is $y=-\frac{-3x}{4}-1$ .

Solution:

Given data: slope = $-\frac{3}{4}$ and y-intercept = –1

y-intercept means (x, y) = (0, –1)

Equation of a line for slope intercept form: $y-y_1=m(x-x_1)$

Here, $x_1=0, y_1=-1$ and $m=-\frac{3}{4}$ .

⇒ $y-(-1)=\frac{-3}{4} (x-0)$

⇒ $y+1=\frac{-3}{4} (x)$

Do cross multiplication.

⇒ $4(y+1)=-3x$

⇒ $4y+4=-3x$

⇒ $4y=-3x-4$

Divide both sides of the equation by 4.

⇒ $y=-\frac{-3x}{4}-\frac{4}{4}$

⇒ $y=-\frac{-3x}{4}-1$

Hence the slope intercept form is $y=-\frac{-3x}{4}-1$ .

What is the midpoint between -2-3i and 3+9i

Svetlanka [38]

Answer:

1/2 + 3i is the midpoint between -2-3i and 3+9i.

Step-by-step explanation:

Given the complex number

-2-3i

3+9i

The formula to find the midpoint of two complex number (a + bi) and (c + di) is:

$M=\frac{\left(a+c\right)}{2}+\frac{\left(b+d\right)i}{2}$

$M=\frac{\left(-2+3\right)}{2}+\frac{\left(-3+\left(9\right)\right)i}{2}$

$M=\frac{-2+3+\left(-3+9\right)i}{2}$

$M=\frac{1+6i}{2}$

$M=\frac{1}{2}+3i$

Therefore, 1/2 + 3i is the midpoint between -2-3i and 3+9i.

What is the equation of a line that is parralel to y= -5x+6 and passes through the point (-4,-1)

mafiozo [28]

Answer:

y = -5x-21

Step-by-step explanation:

Slope of parallel lines is the same.

To find b:

y = mx + b

Substitute the slope and the point given

-1 = -5(-4) + b

Solve for b

-1 = 20 + b

b = -21
