Convert to slope/intercept form (y=mx+b) and find slope y =a/b. 1.3X-2y=14 2. 12X=4y-8. 21-6x=-3y
just rearrange terms as needed.
3x-2y=14
2y=3x-14
y = 2/3 x - 14/3
the others are done likewise.
Wow that's it? Well thanks!:))))
To convert the given equations to slope-intercept form (y = mx + b), we need to isolate the y variable on one side of the equation.
1. 1.3X - 2y = 14
Begin by moving the term with x to the other side of the equation:
-2y = -1.3X + 14
Next, divide both sides of the equation by -2 to solve for y:
y = (-1.3X + 14)/-2
Simplify the right side of the equation:
y = 0.65X - 7
So, the equation 1.3X - 2y = 14 can be written in slope-intercept form as y = 0.65X - 7, with a slope of 0.65.
2. 12X = 4y - 8
Begin by moving the constant term to the other side of the equation:
12X + 8 = 4y
Next, divide both sides of the equation by 4 to solve for y:
3X + 2 = y
Rearrange the equation to have y on the left side and simplify:
y = 3X + 2
So, the equation 12X = 4y - 8 can be written in slope-intercept form as y = 3X + 2, with a slope of 3.
3. 21 - 6X = -3y
Begin by moving the constant term to the other side of the equation:
-6X = -3y - 21
Next, divide both sides of the equation by -3 to solve for y:
2X = y + 7
Rearrange the equation to have y on the right side and simplify:
y = 2X - 7
So, the equation 21 - 6X = -3y can be written in slope-intercept form as y = 2X - 7, with a slope of 2.
To find the slope of the equation y = a/b, you can identify that the coefficient in front of the x variable represents the slope. In the equation y = a/b, the slope would be a/b.
