Question

how can draw a graph ​

Answer 1

Answer:

This is too hard to show you the graph properly.

As you have a large y intercept It couldn't be graphed on paper by me.

Sorry for that.

Step-by-step explanation:

You know, the slope-intercept form of a linear equation is y = mx+c.

Where m is the slope and c is the y intercept. Y intercept is the value what the line intersects. It is when the X value is 0.

For your first equation $y = 160 - 2x$

Look if you plug 0 into this equation you will get 160. So the Y intercept of your graph will be at y = 160. Here is a graph for that equation:
