to find slope, change the equation to
Y = mX + C format, where m is the slope or Tangent of the angle
so from your first equation we get
2x-5y=10
or -5y=-2x+10
or 5y=2x-10
or y = 2/5 x - 2
so slope is 2/5
in second equation, we have x= -2
which is a perpendicular line to x axis, and thus slope is infinite
Hope this come to your help
cheers :)

convert the first equation so y is the subject of the formule
2x-5y=10
-5y=10-2x
5y= -10+2x
y= -2 +(2/5)x
The slope is 2/5
The slope an equation where there is just x like x=-2 or x=3 or x=a number, the slope is infinity

Y= MX + B where M is the slope so
2X - 5Y= 10
-5Y= 10 -2X divide by -5
Y = -2 + 2/5X or
Y = 2/5X -2
slope is 2/5

it is 2 over 5
because 2x=5y>y=2x:5 so it is 2 over 5

C'mon, TJ. In the x = -2 problem the slope is undefined.
You tell 'em the slope is infinite and they'll *never* understand the difference between 'infinite' and 'undefined' âº

slope= (-coefficient of x)/(coefficient of y)
so for first case, slope= -(2)/(-5)=2/5
in the second case coefficient of y is zero.so
slope=-1/0 which is infinity

Don't cheat yourself out of a good education. Open your text book and do your own homework.
