What is 3x y equals 4 and x y equals 0?
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
What is the order pair of y equals x plus 7?
y=x+7 x - intercept set y to 0 0=x+7 -7 -7 -7=x (-7,0) y - intercept set x to 0 y=0+7 y=7 (0,7) (-7,0) , (0,7)
What is the y-intercept of 3x plus 2y equals x plus y?
3x + 2y = x + y y = -2x to find y-int set x equal to zero y = -2(0) = 0 or... 3(0) + 2y = (0) + y 2y - y = 0 y = 0 y-intercept is zero
When does the line y equals x plus 6 cross the y axis?
at y=6.Make x==0 // then you get the y interceptthen y=0+6solve for y, y=6
Where do the lines 5x 3y 20 and 2x - y -14 intersect?
By Simultaneous Equations. Assuming you mean 5x + 3y + 20 = 0 2x - y - 14 = 0. We will eliminate 'y' by multiplying the bottom eq'n by '3' and then adding. Hence 5x + 3y + 20 = 0 6x - 3y -42 = 0 Add 11x -22 = 0 11x = 22 x = 22/11 x = 2 when x= 2 2(2) - y - 14 =0 4 - y - 14 = 0 -y - 10 = 0 y = -10 So the point of intersection in ( x.y.) form is ( 2, -10).
