14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form

-8x-6y=-18

7y = - 14 x + 49 divide with 7 on both sides , then we get y = - 2 x + 7 which is the form y = m x + c ( slope intercept form ) where m = slope and c = intercept so slope m = -2 for given line

y=-(8/7)x+4 Therefore, the slope= -(8/7)

-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7

2x-7y=14 2x-14=7y from this equation the slope is 2/7

y=-(8/7)x+4 Therefore, the slope= -(8/7)

If the equation is x + 7y = 14 then the slope is -1/7 If the equation is x + y7 = 14, then the slope is 7(14 - x)-8

Remember that slope-intercept form is: y = (slope)x + b 9x - 7y = 4 1) First, subtract 9x on both sides. -7y = -9x + 4 2) Then, divide both sides by -7. y = 9/7x + 4 3) There is your answer: y equals nine sevenths x plus 4.

8 over 7.

-7y + 21 = 3x Add '7y' to both sides 21 = 3x + 7y Subtract '3x' from both sides 21 - 3x = 7y 'Swop around'. 7y = -3x + 21 Divide both sides by '7' y = -(3/7)x + 3 The slope of a straight line is the coefficient of 'x' In this case it is ' -3/7'.
