This is a very big question!
Answer:

Step-by-step explanation:
Notice that with the provided information they are given you not ust the slope of the line (-2), but also the y-intercept (the point where the line crosses the y-axis which happens when x=0).
So you can directly write the equation of the line in slope-intercept form [
where "m" is the slope and "b" the y-value when x=0].
Such gives us:

Answer:
Hope this helps!
Step-by-step explanation:
PLs remember to mark brainliest!
Y = mx + b
m = slope
Y = 4x + b
You can see 4 is the slope
Solution: 4
Answer:
33v - 48
Step-by-step explanation:
- 9v - 6(8 - 7v) ← multiply each term in the parenthesis by - 6
= - 9v - 48 + 42v ← collect like terms
= 33v - 48
