The rate of change would be 1.5
y = -1.47585741 or y = 0.22585741 (to 8 dp)
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
y is reduced by 3 units for every increase of 1 in x.
15x + 6y = 45 6y = -15x + 45 (move y to left-hand side) y = (-15/6)x + 45/6 (divide by coefficient of y, 6) y = (-5/2)x + 15/2 (reduce fractions) This is your final answer. your slope is -5/2 and your intercept is 15/2.
If you mean: y = -15x+60 then 15x+y = 60 When y = 0 then x = 4 When x = 0 then y = 60 Coordinates of the line are: (4, 0) and (0, 60)
The rate of change equals the slope. In the basic formula y=mx+b, the rate of change is equal to m. In the equation y=5x+3, the rate of change equals 5.
If 'y' equals 3 plus 10, then 'y' equals 13 ... today, tonight, and tomorrow, until the cows come home, pigs fly, and hell freezes over. 'Y' does not change, so its rate of change is zero.
Sounds like a system of equations. Y + 5X = - 2 - 15X - 3Y = 6 substitution using first equation Y + 5X = - 2 Y = - 5X - 2 ==========insert into other equation as this is Y - 15X - 3(- 5X - 2) = 6 - 15X + 15X + 6 = 6 ========================This looks to be a dependent system that has an infinite number of solutions
y = -1.47585741 or y = 0.22585741 (to 8 dp)
3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
15x + y =65divide by 65 b/s3x/13 + y/65=1ORx/4.33 + y/65=1HENCE X INTERCEPT=4.33 AND Y=65
The y-intercept is whatever number (with no variable) is added onto the end of the equation y=mx+b. In this case b is the y-intercept. In y=15x the y-intercept is 0 because there is no number without a variable on the end.
The second equation has the steeper slope.
