I'm studying for a test, and i can't seem to remember how to find missing coordinates. here's one example of the question,

fill in the other coordinate for the line 3x-5y=2 (2,) i need to find y. i thought that my answer was 4/5 (4over5) i did, 3 times 2, (6) -6 on both sides, so then i had -5y = -4. so i divided both by 5. . but that doesn't sound right to me! anyone know what i'm doing wrong? or right? !

here's another one by the way . y = 3x + 2 (1,)

Under normal conditions, 1.5 feet of snow will melt into 2 inches of water. during a winter season high in the mountains, 301 feet of snow fell. how many inches of water will there be when the snow melts?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Which type of graph would allow us to quickly see how many students between 100 and 200 students were treated?
