54x1 and 6x9 = 54
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)
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)
48or it could be 18 if it was 6x(9-6)
a = 3 and y = 0
y=9x=3it equals ......y= 3.334
x equals y
y=9
The y-intercept equals 0.
-17 + y,,must be equals to..-17y..
