I have a few question on graphing. Could someone tell me if I'm right or wrong? if wrong, correct my answer? Thanks.
a) The line through the points (-2,7) and (3,1) are on a graph. What is the slope of any line that is perpendicular to this line?
m=6/5, m= -6/5, m=5/6, m= -5/6. I have -6/5 is this correct? if not, what is?
b)the graph of the equation 4y= -3/2 is graphed and plotted. What is the slope of this line? m=4, m= -3/2, m= 3/2, m= -3/8 I selected 3/2 is this right? if not, what is?
c)plot a point other than (4, -3) on the line with slope m=0 that passes through (4, -3). I plotted a dot directly in the center of (0,0) because I was confused on this, whats the correct coordinates?
d)the table contains ordered pairs whose coordinates satisfy the equation 2x + y =5, plot the pairs. What are the coordinates of each pair?
x column | y column
0 | 5
-2 | 9
2 | 1
