4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form

4x+5y = 20 5y = -4x+20 y = -4/5x+4 So the slope is -4/5 or as -0.8 and the y intercept is 4

4x + 5y = 20 5y = -4x + 20 y = (-4/5)x + 20/5 Now that the equation has been rewritten in standard form, the slope is the cofficient of x, -4/5 [or -0.8]

-4x + 5y = 10Add 4x to each side:5y = 4x + 10Divide each side by 5:y = 0.8x + 2The graph of this equation is a straight line with [ slope = 0.8 ] and [ y-intercept = 2 ].

- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------

It is: 7x+10y

Let's see. 4X - 5Y = - 20 - 5Y = - 4X - 20 Y = 4/5X + 20 slope(m) = 4/5 Is positive

I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2

It is an expression that can be simplified to 5y+2x-6

It is simple if you put it in slope-intercept form. y=mx +b is where m=slope and b=y-intercept -4x+5y=20 bring the 4x over to the other side 5y=4x+20 divide both sides by 5 y=4/5x+4 y=mx+b b=4 y-intercept=4
