Answer:
The line crosses the y-axis at -2
Step-by-step explanation:
y = mx + b 'm is the slope and b is the y-intersect (the place where the graph comes across the y-axis.
y = mx + b; y = mx + b; b = -2.
Answer:
7 is a obtuse and 2 is acute
Answer:

Step-by-step explanation:
In this problem, we have that:

So we can see this as an equation that comes from matching two equations, these two equations are:

Therefore, by matching
, we'll find the y-value at which these two functions intersects, that is:

Answer:
Yes you are
Step-by-step explanation:
If you multiply the first equation by 3 , y becomes 3y and so you can eliminate from there.
