Question

HELP PLEASE WILL FAN AND MEDAL!:)
Attaching a pic, i need someone to explain how I would get the answer.

Answer 1

3x-4y=-4

Answer 2

@macabbey101
You are correct.

Answer 3

thank you. but how would i get the answer

Answer 4

Guys, she wants to know how to get the answer, not that it is correct.

Hi @macabbey101, can you tell me the equation of a straight line?

Answer 5

what do u mean? @tom982

Answer 6

Do you know the general equation of a straight line?

Answer 7

We need it here.

Answer 8

y=mx+c

Answer 9

There are several ways of doing it.

Here is one way.

The point-slope equation of a line is:

\(y - y_1 = m(x - x_1)\)

where m is the slope, and \((x_1, y_1)\) is a point the line passes through.

Answer 10

yes I know that :)

Answer 11

In your case, you can find two points on the line and find the slope.

The slope of the line that passes through points \((x_1, y_1)\) and \((x_2, y_2)\) is

\(m = \dfrac{y_2 - y_1}{x_2 - x_1} \)

Answer 12

Let's pick two points on your line.
We look at the graph, and we pick two points that are easy to read.
A point is easy to read when its x- and y-coordinates are on grid intersections.

We can use the two points marked on the line.
The left point is (-4, -2)
The right point is (4, 4)

Can you use those two points and find m, the slope of the line?
