Recall that an equation in slope-intercept form is as follows:
where m is the slope of the line, and (0,b) is the y-intercept.
Substituting m=-6, and b=-1/2 we get:
Simplifying the above result we get:
Answer:
If the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)
Given,
The vertices of the triangle = J(-3,-5), K(-2,2) and L(1,-4)
We know,
In reflection in y axis (x,y) will become (-x,y)
Then the vertices of the reflection in y axis = J(3,-5), K(2,2) and L(-1,-4)
Draw the triangle using the vertices.
Hence, if the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)
