Not sure how to do it in this form but in slope intercept form for example if the slope was -4/3 the perpendicular would be 3/4 it’s the negative reciprocal of the answer
I thinks 5 because -2(x) = -2x and -2(5)=-10
So -2x=-10
-10/-2=5
X=5
Answer:
2.2y-2x = 0
Step-by-step explanation:
The standard form of the equation is normally y = mx + c where m is the gradient or the slope value while c is the y intercept.
As we know, the line passes through the origin, hence, it has no y intercept. This means our c has a value of zero.
What is left to find is the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (2 - 0)/(5 - 2.8)
m = 2/2.2 = 0.9091
so the standard form of the equation of the line is y = 0.9091x
OR
y = (2/2.2)x
OR
2.2y = 2x
