You can put this solution on YOUR website! 1) Find an equation of the line.Write the equation in standard form. With slope of -4/7, through (5,3)
 Form: y = mx+b
 3 = (-4/7)5 + b
 21/7 + 28/7 = b
 b = 7
 ------
 Equation:
 y = (-4/7)x + 7
 4x + 7y = 49
 a) 7x+4y = -41
 b) c) 4x + 7y = 49
 c) 4x + 7y = -41
 ---------------------------
 2) Find the slope of the line.
 through (-3,3) and (-8,-9)
 slope = (3--9)/(-3--8) = 12/5
 a. 6/11
 b. 12/5
 c.5/12
 ---------------------------------
 3) Find the slope of the line.
 7x +y = -1
 y = -7x - 1
 slope = -7
 a. -1/7
 b. 7
 c. -7
 4) Determine the slope and the y-intercept of the graph of 10x - 8y = 80
 a. 4/5; (0,8)
 b. -5/4; (0,-10)
 c. 5/4; (0,-10)
 5) Find an equation for the line.
 Write the equation in standard form.
 Through the origin and (-8,-5)
 y = (5/8)x
 5x - 8y = 0
 a. -5x - 8y = 0
 b. 5x - 8y = 0
 c. -8x + 5y = 0
