y = -6x - 30
At the "x-intercept", 'y' is zero.
0 = -6x - 30
Add 6x to each side of the equation:
6x = -30
Divide each side by 6 :
x = -5
At the x-intercept, y = 0
Hence
y = - 6x -30
0 = -6x - 30
6x = -30
x = -5

If y equals 6x and x equals 1.5 what is y?
y=9
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.

What are the x- and y-intercepts of the line with equation 4x plus 5y equals 40?
First, put the equation in slope-intervcept form y=mx + b 5y=4x + 40 The y intercept is where x=0 so- 5y= 4(0) +40 solve for y y intercept = (0,8) For the x intercept, y=0 0=4x+40 -4x=40 x= -10 xintercept =( -10.0)
What is the xintercept for 5x - 4y equals 18?
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
If 3 plus y equals a 3-y equals a then a equals y equals?
a = 3 and y = 0
What does y equals 9x equals 3 equal?
y=9x=3it equals ......y= 3.334
What is the answer for y equals x?
x equals y
What is the xintercept of y2x 5?
As written this is not a graphable thing. I does not represent a graphable equation because there is no "=" sign. Whatever the equation might be, the x intercept is found by setting y=0, which leaves you with an equation for x, which is the intercept.
If y equals 6x and x equals 1.5 what is y?
y=9
What is the y intercept for y equals -2x?
The y-intercept equals 0.
