you can do 2:4 all you need to do is multiply both numbers by the same number!
please mark me brainlyest if i helped
For number 9 just take the two functions and multiply or add them I can’t tell what sign that is
Answer:
9
Step-by-step explanation:
divide 18 my 2 since its between 0 and 18
Answer:
1
Step-by-step explanation:
1) First, place the given equation in slope-intercept form (
format) to find its slope easier. Isolate the y:
So, the equation of the line in slope-intercept form is 
. When an equation is in slope-intercept form, the 
, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.
2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.
To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as 
-- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
I think your answer would be -7.9 hope that helps!
