y = 3x - 2 ; x ≥ 0
In order to graph this linear equation, you must solve for y to determine
(x,y) points on the graph.
You already know that x can equal or be more than 0, and that's a great starting place.
Draw a giant T and use whole numbers to substitute...
Let's try it this way:
At some point in time in the past indicates that we need to use subtraction.
Let X = how many years ago Jean was 4 times as old as Sal
Jean is 40 - X; Sal is 13 - X
40 - X = 4 ( 13 - X )
Solve for X
y = mx + b where m is the slope and b is the y-intercept
substitute what you have been given, 3/4 slope; y-intercept -35
y = 3/4 x + (-35)
Set up an x ! y chart to determine points for graph
Find the slope for
3x + y = -8
Okay, let's put it in y = mx + b format first (the equation of a straight line, slope-intercept form)
where m is the slope and b is the y-intercept
Subtract 3x from both sides to isolate y.
This question is challenging to respond to because you have not given us the equation or problem.
What I would like to assume is that it might look something like this:
y = x + 2
If this is the case, you substitute 4 in every place you find an x.
Every complete sentence contains two parts: a subject and a predicate.
Blanchard successfully made the first human parachute drop in 1793.

What is Half of 2/3?
"of" means "times"
1/2 x 2/3 = 2/6 = 1/3

-4x + y = 7
Solve for y.
Add 4x to both sides.
+4x - 4x + y = 7 + 4x
y = 7 + 4x or y = 4x + 7
You have now solved for y.
"Discuss the merits" means that you must justify the statement by citing specific examples.
1. I recommend that you use a Thesaurus and substitute synonyms for all difficult vocabulary.
(i.e., melancholy= depression, gloom ; aspiration=...
7y= x + 2
Solve for x
Subtract 2 from both sides
7y - 2 = x
Plug this equation into the next one using 7y - 2 for x
4x - 8y = 12
4(7y - 2) - 8y = 12
28y - 8 - 8y = 12
20y - 8 = 12
20y = 20
y = 1
Now plug 1 into y in either equation to solve for x
7y - 2 = x
7 - 2 = x
Both answers above are great.
It just depends upon how your teacher wants you to solve the problem.
Here is one more way:
2/3 * (4x - 1) = -22
multiply the left side out
(2/3 * 4x) + (2/3 * -1) = -22
8x/3 - 2/3 = -22
Now you can do one of two things:
1. Find a...
