This looks familiar, right? Like slope-intercept.
y=mx+b, where m is the slope.
Let's right it like that.
5y=3x-10 (add 3x to both sides, since we want to isolate the y.)
Now divide by 5, since - again - we want to isolate the y.
y= 3/5x-10/5 >>>> y= 3/5x-2
I think the slope is 3/5.
If the line happens to be parallel, the slope is the same. If perpendicular, it is opposite reciprocal. So if it was perpendicular, the slope would be -5/3.
The slope can be found re-writting the function in the general format s y=mx+n where m is known as slope. For this case:
-3x+5y=-10, trasponding the x term
5y=3x-10, dividing by 5
y=3x/5-10/5, solving finally have the general format:
y=3/5x-2
Then the slope is the number that precede the x unknow.
Solution. The slope is 3/5.
