Please answer with clear instructions so that i can apply this to other questions
marishachu [46]

Answer:

1 and - 1

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope ( gradient ) )

y = x ← is in this form

with gradient m = 1

Parallel lines have equal gradients

Then the gradients of lines parallel to the given line is 1

Given a line with gradient m then the gradient of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{1} = - 1

Then the gradients of lines perpendicular to this line is - 1

Coefficient of 24x+32+4x+3
coldgirl [10]

Firstly, you can combine like terms, or terms that have the same variable and exponents.


24x and 4x both have the variable "x" so it can be combined to make 28x


A coefficient is basically just the number that's used to multiply the variable

In this case, the variable is "x" and the number that will be multiplied to x is 28.


<em>The coefficient is 28.</em>
