. Write an equation for the line parallel to y = 7x + 11 that contains P(-5, 7).

m_a_m_a [10]

A) x – 7 = -7(6y + 5)

x – 7 = -42y + -35

x – 7 + 35 = -42y

x + 28 = -42y

y = (1/42)x – 14/21

c) y – 7 = 7(x + 5)

y – 7 = 7x + 35

y = 7x + 42

b) y – 7 = -7(x + 5)

y – 7 = -7x -35

y = -7x – 28

d) y + 7 = 7(x + 5)

y + 7 = 7x + 35

y = 7x + 28

What is 5x-4y=-7 (-20,-8)in slope intercept form

forsale [732]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following equation:

$5x-4y = -7$

We manipulate algebraically to write the equation of the slope-intersection form:

$-4y = -7-5x\\4y = 5x + 7\\y = \frac {5} {4} x + \frac {7} {4}$

We check if the given point belongs to the equation:

$y = \frac {5} {4} (- 20) + \frac {7} {4}\\y = -25 + \frac {7} {4}\\y = \frac {-100 + 7} {4}\\y = - \frac {93} {4}$

The point does not belong to the equation.

ANswer:

$y = \frac {5} {4} x + \frac {7} {4}$
