Question

I need help it's due in 2 hours I'm confused on the last question. I mainly need help with knowing what to do with y=-1​

Answer 1

Explanation:

Hope this is helpful

y=-1 is nothing but it's the y value by using that we have to find the x value

Answer 2

Answer: I am not sure exactly what you need as there is no context

-> See attached for graph

-> They intersect at point (2, -1)

Explanation:

To answer your question of "I mainly need help with knowing what to do with y=-1​" you will graph it as you do with y = -
`(5)/(2)`x + 4.

Any y = something equation will be a horizontal line. There is no slope, the "mx" chunk, so the line stays straight. You will put a dot at (0, -1) and draw a line straight from that point.

For y = -
`(5)/(2)`x + 4, place a dot at (0, 4) and then count down 5 units and 2 units to the right to place another dot. Then draw a line through these two dots and extend it beyond to create the line.
