Question

Graph the equation by plotting 3 points
-5x - 3y=-7

Answer 1

-3y = 5x - 7
3y = -5x +7

now put x = 2
3y = -10 + 7
y = -3/3 = -1
first point is (2,-1)

now put x = -1
3y = 5 + 7
y = 12/3 = 4
second point (-1,4)

Answer 2

First rearrange the equation to the form y=mx+c.
\[-5x-3y=-7\rightarrow5x+3y=7\rightarrow3y=7-5x \rightarrow y=\frac{7}{3}-\frac{5x}{3}\]

Then you can read off the y intercept which is c

or just plugin values for x to get 3 points

Answer 3

Here is a graph so you can check your points

Answer 4

now put x = 5
3y = -25 + 7
y = -18/3 = -6
so third point is (5,-6)

Answer 5

@MiMi

You can plot the three points given by me and join them by a line to get the graph....

Answer 6

should the line match?

Answer 7

okhay thanks it was right

Answer 8

match what ??
