Answer:
Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph
is below

Step-by-step explanation:
Slope of the equation
is 
Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as

Equation of line in point slope form is given as

Here (x1, y1) = (4, -8)

Simplifying it further


Answer:
t≥-25
Step-by-step explanation:
this is becuaset ≥ -25 shows that it can not fall under -25, but can be equal to -25.
-2 = -(x-8)
-2 = -x + 8 ( - * + = - and - * - = + )
-2 - 8 = -x +8 - 8
-2 - 8 = -x
-(2+8) = - x
-10 = -x | * (-1)
x=10
Answer:
132°
Step-by-step explanation:
because the lines are parallel x + 48° must be 180°
therefore x = 132°
