Answer:

a) y=2x+4 b) 2 c) 6 d) Sorry, you'll have to do that buy it's not too difficult! ^u^

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

1a) Well, if you add the y to both sides, you would get y=2x+4

1b) Since the main form is y=mx+b with m being the slope, the slope in y=2x+4 must be 2

1c) 6, because if x is 1, 2(1)+4=6

1d) I'm afraid you'll have to do that, just substitute in different numbers for x

kherson [118]
To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:

4 \frac{2}{3}  \times 1 \frac{1}{4}  \\  =  \frac{14}{3}  \times  \frac{5}{4}  \\  =  \frac{70}{12}  \\  = 5 \frac{10}{12}  \\  = 5 \frac{5}{6}
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!
