The question is not clear, but I’ll take my best guess:
4+ 85y -12 = 0
85y= 8
y= 8/85 (which you can divide to get a decimal answer)
Perpendicular lines are lines that, when intersect the original line, form a right angle. This is formed when two lines' gradients are the negative reciprocals of each other.
In essence,
Now let 5 be
Thus,
That means any line with a gradient or slope of
is a line that is perpendicular to this line.
In essence, the general equation would be:
Answer:
Step-by-step explanation:
equation of line formula:
m = slope
c = y-intercept
1) find m
slope formula:
take 2 coordinates from the given graph and substitute the values into the slope formula
i) (-1,0)
ii) (3,2)
substitute the values into the slope formula
2) find the half equation of the line by substituting the value of m into the equation of line formula
3) find c by substituting either coordinate into the half equation
(3,2)
x = 3
y = 2
4) find equation of line by substituting the value of c into the half equation
I’m pretty sure it’s answer a!
Distribute, then you get 3x+6-2x 4 then combine like terms and use your graphing calculator to graph
