Answer:

\boxed{\large\sf y = 3x - 5}

Step-by-step explanation:

Here we are given a equation which is ,

\longrightarrow  y = 3x + 6

We need to find out the equation of the line which is parallel to the given line and passes through the given point .

  • And as we know that the slope of two parallel lines are equal .

On comparing the given equation with slope intercept form (y = mx + c )of the line , we have ,

\longrightarrow m = 3

Therefore the slope of the parallel line will be ,

\longrightarrow m_{||}= 3

Now we can use the <u>point </u><u>slope </u><u>form </u>of the line which is ,

\longrightarrow y - y_1 = m(x - x_1)

Substitute ,

\longrightarrow y - 7 = 3 ( x -4)\\\\\longrightarrow y -7 = 3x -12 \\\\\longrightarrow y  = 3x -12+7\\\\\longrightarrow y = 3x -5

This is the required answer .

Olin [163]
When finding the area of a rectangle, you do area=length*width
length= 3
width= 1/4
a= 1/4*3
a=3/4 square feet
