(7,12)
This cannot have an answer. "7y12" is not correct. If you put a plus before the twelve, this is how you solve it. y=m(slope)x(independant variable)+b(y intercept) 3x-7y+12 +7y 7y=3x-12 /7 /7 /7 y=3/7+1.714285 repeating 1.714285 repeating is the y intercept of there is a minus sign, just switch the positive on the y intercept.

y intercept 7 x intercept 7/3
The slope intercept form is: y = mx + b 9x + 7y = 15 9x - 9x + 7y = 15 - 9x 7y = - 9x + 15 y = -(9/7)x + 15/7
This form. Y = mX + c- 2X - 7Y = - 2- 7Y = 2X - 2Y = (- 2/7)X + 2/7==============Y intercept = 2/7----------------------
(7,12)
Put in this form. Y = mX + c3X - 7Y = 8- 7Y = - 3X + 8Y = (3/7)X - 8/7===========Y intercept = - 8/7-----------------------
x + 5y = 75y = -x + 7y = -(1/5)x + (7/5)The y-intercept of this line is +(7/5) or 1.4There is no negative y-intercept.
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
It is: y = -8/7x+3/7 in slope intercept form
2x + y = 7y = -2x + 7
y-intercept = 3y-intercept ; x = 07y + 3x - 21 = 07y + 3(0) -21 = 07y -21 = 07y = 217y/7 = 21/7y=3
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.
Remember, the y-intercept is where the x-value is equal to zero. The easiest way to do this is to solve an equation in terms of x, for y. -7y + x - 1 = 5x + 15 -7y = 5x - x + 15 + 1 -7y = 4x + 16 y = (-4/7)x - 16/7 Now that you have solved an equation for y, simply substitute 0 in for x to find the y-intercept. y = (-4/7)(0) - 16/7 y = 0 - 16/7 y = -16/7 This is the y-coordinate of where your y-intercept will occur. Since it is a y-intercept, the x-value is 0, giving you the ordered pair ( 0 , -16/7 ).
It's the equation of a straight line, with a slope of (6/7) and a y-intercept of (-12/7).
