Answer:
-5 as the gradeint because y=mx+c in which m is the gradient
Step-by-step explanation:
Answer:
Step-by-step explanation:
Equations a, c, and d are all linear. They take the form of y = mx + b.
b. 4xy + 3 / x = 12 is nonlinear, due to the (3/x) term. See attachment.
y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4
