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 
and 
in the general formula by their coordinated counterparts, and replacing 
by the slope that is given to you.
Let's assume the coordinates you are given are 
, and the slope you are given is 1.
By substituting into the general formula...
...we can see that it is possible to find the y-intercept (
).
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.
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.
Answer:
A.) 5000p-2700p= 2300p B.) 5000p-2700p-400p=1900p
Step-by-step explanation:
A. Is how many points you need after having the 2700. B. Is how many points you need after depositing the money. p=points
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
