What can I do with a coordinations and the slope
Mnenie [13.5K]

You can plot a linear equation, if you are given the coordinates and the slope for THE SAME line.

Assuming you have those, the first step is to find the y-intercept.

That is done by replacing x and y in the general formula by their coordinated counterparts, and replacing m by the slope that is given to you.

Let's assume the coordinates you are given are (5,10), and the slope you are given is 1.

By substituting into the general formula...

y=mx+c\\(10)=(1)(5)+c\\10=5+c\\10-5=c\\c=5

...we can see that it is possible to find the y-intercept (c).

Knowing the y-intercept, it is possible to plot the line and solve any question.

I'll leave a picture of the example used above when graphed.

The sum of 2 consecutive odd integers is 92. Find the numbers.
kifflom [539]

Answer: If x is odd then x + 2 is going to be the next odd integer

Step-by-step explanation:

Set up the equation and solve.

x + x + 2 = 92 This is the equation. Collect like terms.

2x + 2 = 92 Subtract 2

2x = 90 divide by 2

x =45

x + 2 = 47

45 + 47 = 92.  

So x + 2 is the next odd number after x.

Naddik [55]
Let x be the length of one leg ⇒
<span>By the Pythagorean theorem:</span>

x² + x² = (10√5)²
2x² = 500
x² = 500/2
x² = 250
x = √250 = 5√10
