What is the y-intercept of 7y 3x-21 equals 0?
y-intercept = 3y-intercept ; x = 07y + 3x - 21 = 07y + 3(0) -21 = 07y -21 = 07y = 217y/7 = 21/7y=3
What is the slope of 4x-7y-28 equals 0?
If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
6y -3x - 2 Slope?
If the equation is 6y - 3x - 2 = 0 6y - 3x - 2 = 0 6y = 3x + 2 y = (1/2)x + 2 The slope is 1/2. If the equation is 6y = -3x - 2 y = -(1/2)x - 2 The slope is -1/2.
What is the slope intercept form of the equation of a line with slope 1 over 3 and y intercept 0 -4?
y = 1/3x-4 in slope intercept form
How do you find the y intercept of a line with only slope?
tough to answer, but if slope is only provided then it should intercept at (0,0). Such as, y=3x, that intercepts at 0.
What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
What is the slope of a parallel line to -3x - 7y equals -8?
Parallel lines have the same slope. -3x - 7y = -8; the slope = -(-3/-7) = -3/7. Thus any line with slope of -3/7 is parallel to -3x - 7y = -8. Exampes: -6x - 14y = 0 -3x - 7x = 2 etc.
What is the y-intercept of 7y 3x-21 equals 0?
y-intercept = 3y-intercept ; x = 07y + 3x - 21 = 07y + 3(0) -21 = 07y -21 = 07y = 217y/7 = 21/7y=3
What is th y intercept of 7y plus 3x-21 equals 0?
3
What is the slope of the line y equals 3x?
Slope=3, y-intercept=0. y=3x or y=3x+0
What is the slope of 4x-7y-28 equals 0?
If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
What is the area of a triangle formed when the line 3x -7y plus 4 equals 0 meets the x and y axes?
If: 3x-7y+4 = 0 then 3x-7y = -4 The intercepts are at: x is at (-4/3, 0) and y is at (0, 4/7) Distance of x from the origin: 4/3 Distance of y from the origin: 4/7 Area of the triangle: 1/2*4/3*4/7 = 8/21 square units
How do you solve this problem -3x plus 7y equals -1 -2x plus 5y equals 0?
-3x + 7y = -1 -2x + 5y = 0 What I would do is split the equation into two and label them: [A] -3x + 7y = 0 [B] -1 -2x +5y = 0 Now change [B] so that the number term is on the other side (not essential, but it makes it a bit cleaner) [B'] -2x + 5y = 1 Now you can use elimination to get rid of either x or y. I'm going to do it for x, but first you need to make the numbers on the x's the same. So we multiply all of [A] by 3 and [B'] by 2: [A'] -6x + 14y = 0 [B''] -6x + 15y = 3 Now you can subtract one from the other and since the x terms are the same, they will cancel out. I'm going to subtract [A'] from [B'']. -6x - (-6x) + 15y - 14y = 3 - 0 so y = 3 Then you put y back into one of the equations, for example [A]: -3x + 7y = 0 -3x + 7(3) = 0 -3x + 21 = 0 -3x = -21 3x = 21 x = 7 hence x = 7, y = 3
What slope o the parallel line of -5x-7y-6?
Slope is found by this form. Y = mX + c ( m = slope ) - 5X - 7Y - 6 = 0 ( I assume this is what you mean ) - 7Y - 6 = 5X - 7Y = 5X + 6 Y = - 5/7X - 6/7 The slope would be in this instance, - 5/7 ----------
What is the area of a triangle formed by the line 3x -7y plus 4 equals 0 when it meets the x and y axes on the Cartesian plane?
Equation of line: 3x-7y+4 = 0 Base of triangle: 4/3 Height of triangle: 4/7 Area of triangle: 0.5*4/3*4*7 = 8/21
What is the answer to 3x-7y equals 12?
x=0 and y=12\7
What is 18 equals 39-7y equal -with the work shown?
18=39-7y minus 18 from both sides (0=21-7y) subtract 21 from both sides to get the variable and the number on opposite sides -21=-7y -21/-7y= ____ y= ___
