Start by multiplying -4/5 by everything in the Perenthises, These> ()
Which gives you y+5=-4/5+3.2
Then you rearange the equation to where y is alone, so move the five to the other side of the equal sign (Remember: When changing sides, the signs always change)
Then you'll get the slope intercept form: y=-4/5x+3.2-5
Step-by-step explanation: i just solved it and it was correct. 300-250=50 50 divided by 20 is 2.5. you divide it by 20 because you have to isolate h in 20h by itself. and to do that you divide 20h by 20
