Respuesta :

The y intercept is at  y = 1

Step-by-step explanation:

Step 1 :

Given,  line's equation is  =  Y= - [tex]\frac{3}{4}[/tex] x + 5

Slope of the line perpendicular to this line = [tex]\frac{4}{3}[/tex] [As the product of the slope of 2 perpendicular lines is -1]

The point  (-3,-3) lies  on the line

Hence the new line's equation  can be obtained using the formula

(y - y1 ) = m (x-x1) ,

where (x1,y1) = point on the line

              m    = slope of the line

Substituting,

y + 3 =  [tex]\frac{4}{3}[/tex] (x + 3)

y + 3 =  [tex]\frac{4}{3}[/tex] x + 4

y =  [tex]\frac{4}{3}[/tex] x + 1

Step 2 :

To find the y intercept.

At the point of y - intercept, that is when the line touches the y axis, the x co ordinate = 0

So substituting x = 0 in the line's equation, we have

y = 0 + 1 = 1

y = 1

Step 3 :

Answer :

The y intercept is at  y = 1
