Slope Intercept form is: y=mx+b
Standard Form is: Ax+By=C
Point Slope form is: y-y1=m(x-x1)
Answer:
<em><u>Lines are perpendicular to each other .</u></em>
Step-by-step explanation:
Standard equation of line is : y = mx + c, Where m represents the slope
Given Equations :


Two lines are parallel if the slope of the lines are same.
Two line are perpendicular if the product of the slope = - 1
Clearly slopes are not equal , therefore the lines are not parallel.
product of the slope is - 1, therefore the lines are perpendicular.

Answer:
Slope=-1
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where (X1,y1)(0,8) and (X2,y2) (4,4)
Slope=8-4/0-4
=4/-4
=-1
So slope is -1
