Default ALGEBRA ?s plz last few i need?

16) Describe how you would graph the equation on a coordinate plane –3x + 2y = 4.17) Simplify (3x + 4y) + (2x – 5y) + (-5x – 3y)Name the property that is illustrated in the next problem21) 2x(3y – 4) = 6xy – 8xFind the slope of the line passing through the given points in the next two problems29) (1, 5) and (4, 8) 30) (-5, 9) and (3, -6)Write an equation in slope-intercept form for each line, according to the given information in the next five problems.31) slope of 2 and a y-intercept of –432) containing the point (2, 9) with a slope of (-5/2) 33) containing the points (9, -3) and (0, 5)34) parallel to y = 4x + 2 containing the point (2, -1)35) perpendicular to y = (2/3)x - 8 containing the point (-1, 2)

16) -2x+3y=4 3y=4+2xmake a table of x and y values and plot these on graph paper for example: if x=0 y =4/3 if x=1 y=2 if x=2 y=8/3 etc etc etc17)3x+4y+2x-5y-5x-3y = -4y21) Associative Property29) slope = (8-5)/(4-1)=3/3 = 130) slope = (-6-9)/(3--5)=-15/831)y= mx+b = 2x-432)(y-9)/(x-2)=-5/2 y-9 =-5/2x+5 y= 5/2x +1433)m=(5--3)/(0-9)=8/-9 (y-5)/(x-0) =-8/9 y=-8/9x +534) m=4 ( y-2)/(x--1)=4 y-2=4x+4 y=4x+635) m=-3/2 ( y-2)/(x--1)=-3/2 y-2 = -3/2x -3/2 y= -3/2x +1/2
