Answer:
Step-by-step explanation:
The perpendicular slope of the line(m) = :
The function formula is y = mx + b, where the y-intercept(b) is found by substituting in the values of a point on the line ⇒ (4, -6):
<u>So the perpendicular equation is </u><u>.</u>
Answer: D , -4/7
B
12+x goes to 19
3x+y goes to 25
4y-10 goes to 6
1/2xy goes to 14
x=7 and y=4 all you have to do is substitute for example 12+x substituted it's 12+7 then just do the math. That's it.
