Answer:

The equation would be y = -2x + 8.

Step-by-step explanation:

To find the slope, we need to use the Slope Formula:

m = rise/run = y2 - y1/ x2 - x1

(2, 4) are the coordinates of the first point on the graph, (3, 2) are for the second point.

y2 - y1 (the rise):

2 - 4 = -2

x2 - x1 (the run):

3 - 2 = 1

That makes the slope -2/1 which can be simplified to -2. So far we have, y = -2x. There are multiple ways to find the Y-Intercept, but I'm just going to plug the slope in by multiplying it by the X of the first coordinate:

-2 • 2 = -4

According to the Y of that same coordinate, we need a positive 4, not negative. We need to add 8 to get that positive 4. The Y-Intercept is + 8.

Hope this helps,

Answer: y = − 2 x + 8

Step-by-step explanation:

Use the slope formula and slope-intercept form y = m x + b to find the equation.

y = − 2 x + 8

Convert y = -x + 50 to standard form

elena-14-01-66 [18.8K]

Step-by-step explanation:

First write the given equation

${:}\longrightarrow\sf y=-x+50$

Now take all polynomials to left side.

${:}\longrightarrow\sf y+x-50=0$

Simplify

${:}\longrightarrow\sf x+y-50=0$

How do you do this please help

List the given statements, and then list the conclusion to be proved. Now you have a beginning and an end to the proof.
Mark the figure according to what you can deduce about it from the information given. This is the step of the proof in which you actually find out how the proof is to be made, and whether or not you are able to prove what is asked. Congruent sides, angles, etc. should all be marked so that you can see for yourself what must be written in the proof to convince the reader that you are right in your conclusion.
Write the steps down carefully, without skipping even the simplest one. Some of the first steps are often the given statements (but not always), and the last step is the conclusion that you set out to prove. A sample proof looks like this:
