Tell the answer to, or how to put, y=-3/2x+4 -into standard form
The slope-intercept form is y+=+mx+%2B+b in which m and b are constants, in which m is the slope of the graph and b is the value where the graph intercepts the y-axis.
So what you need to do for the first problem is to move the terms around and solve for y to get the equation to match the slope intercept form.
4x+-+5y+=+10
Move the 4x term to the right side of the equation, by subtracting 4x from both sides. This subtraction cancels out the 4x on the left side and makes a -4x appear on the right side as follows:
++-5y+=+-4x+%2B+10
Now divide all terms on both sides of the equal sign by -5 to get:
y+=+%28-4%2F-5%29x+%2B+10%2F-5
When you divide -4 by -5 the answer becomes positive. And dividing +10 by -5 results in -2. So the answer becomes:
y++=+%284%2F5%29x+-+2
The next problem involves putting an equation into standard form. The standard form is:
ax+%2B+by+=+c
where a, b, and c are all constants. So what you need to do is take the equation you are given, an equation in slope-intercept form, and rearrange things to get it into standard form. You are given:
y+=+%28-3%2F2%29x%2B4
Get rid of the denominator of 2 by multiplying all the terms in this equation by 2 to get:
2y+=+-3x+%2B+8
Next, move the -3x term to the other side of the equal sign by adding 3x to both sides. Adding +3x to the right side cancels the -3x. And adding 3x on the left side makes a +3x appear on the left side. The result is:
%2B3x+%2B+2y+=+8
This is the standard form that you are looking for.
Hope this helps.
