It's the equation of a wavy wiggly line graph that looks like a rope being waved
up and down.
The maximum value of the wavy graph is y=7, the minimum value is y=-7, and the
average is zero ... the x-axis cuts straight through the middle of all The Wiggles.
If 'x' is in degrees, then the graph crosses the x-axis at 22.5 and then again at
every 45 after that.
If 'x' is in radians, then the graph crosses the x-axis at (pi)/8 and then again at
every (pi)/4 after that.
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1

4x - 4y + 7 = 15to get it into y-intercept form do this...4x -4x - 4y + 7 - 7 = 15 - 7 - 4x-4y = 8 - 4x-4y / -4 = (8 / -4) + (-4x / -4)y = x + 2you did not give any values to plug in so this is as best an answer i can give
8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0
y = 4x-3
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
-3
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
4x+y = 7 y = -4x+7 in slope-intercept form So the slope is -4
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
Yes, y = 4x + 7 is a linear equation.
(A): 4x + y = 7 (B): 2x - 3y = -7 2*(B) 4x - 6y = -14 Subtract from (A) 7y = 21 Divide both sides by 7: y = 3 Substitute in (A): 4x + 3 = 7 ie 4x = 4 or x = 1 Answer: x = 1 , y = 3
4x-y+7=0
-7
(2, 7)
x=7 y=4
