The slope of a straight line perpendicular to another is the negative reciprocal
So you have 3x+y = 15
y = -3x+15
here the slope is -3 ( the number in front of the x is slope, m, remember?)
so the slope of the line perpendicular is minus (1/-3) = 1/3
-3/5
The slope of the line that represents the graph of that equation is 15.
y = -1.2x-3 in slope intercept form
It is 3 and the slope is 3/5
The slope is 1/3 and the y-intercept is -1.
-12
this is an equation of a line. it has a slope of 4/3 and a y-intercept of 5
Get in slope intercept form. 3X + 5Y = 15 5Y = -3X + 15 Y = -3/5X + 3 -3/5 is the slope of this line and the line parallel to this line
Equation of given line: 3x + y = 15 or y = -3x + 15 Slope of given line = coefficient of x = -3 Slope of perperndicular = -1/(slope of given line) = -1 / (-3) = 1/3
Rewriting the equation 3x + y = 15 gives y = 15 - 3xThe slope of this and any parallel line is the x multiple, which in this case is -3
5x+2y = 30 2y = -5x+30 y = -2.5x+15 Therfore the slope is 2.5 and y the intercept is 15.
It equals 285
