Massage the equation into the standard form [ y = f(x) ] so that you can read off the slope and y-intercept.
x + 5y = 55
Subtract x from each side:
5y = -x + 55
Divide each side by 5:
y = -(1/5)x + 11
Now you know that the slope of the graph is -(1/5), and the y-intercept is 11.
That should help a lot.
(-5, 2)
The Commutative Property of Addition.
X intercept: -5 Y intercept: +3
x=(-5y-1)/3
5y + 7 = 25y = -5y = -1
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
no
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
No.
It equals x+5y simplified
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
