Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3x + 3.
alexandr1967 [171]

Parallel lines have the same slope, but different y-intercepts

The slope of both lines is -2/3

To find the equation that passes through (7, 3) we can use the point-slope formula: y - y1 = m (x - x1)

y - (3) = (-2/3) (x - (7))

y - 3 = -2/3x + 4 and 2/3

y = -2/3x + 7 and 2/3

or

y = -2/3x + 7.67

Simplify 4sqrt(6) / sqrt(30) by rationalizing the denominator.
daser333 [38]
Given question is 4√6/√30
by rationalizing the denominator
4√6x√30/√30x√30
= 4√6x30/√30²
=4x√180/30 (i)
by solving the √180
√180=6√5
putting the value of √180 in (i)
=4x6√5/30
=24√5/30
=4√5/5 is the right answer.
