PLS HELP:( !! What is an equation of the line
pychu [463]

Answer:

y =  \frac{3}{2} x + 8

Step-by-step explanation:

The given equation is written in the form of y=mx+c (where m is the gradient and c is the y-intercept).

Thus, gradient of given equation= -⅔

The products of the gradient of perpendicular lines is -1.

(Gradient of line)(-⅔)= -1

Gradient of line

=  - 1  \div ( -  \frac{2}{3} ) \\  =  \frac{3}{2}

Hence, m= \frac{3}{2}.

Subst. m= \frac{3}{2}into the equation:

y =  \frac{3}{2} x + c

To find the value of c, substitute a pair of coordinates into the equation:

When x= -4, y= 2,

2 =  \frac{3}{2} ( - 4) + c \\ 2 =  - 6 + c \\ c = 2 + 6 \\ c = 8

Thus, the equation of the line is y =  \frac{3}{2} x + 8.
