Answer: The equation for a line is y = mx + b. B is the y-intercept (where x=0). If your B value is 6, then your y-intercept is (0,6). This is the same with negatives, if you have a negative B value, then the y-intercept is below the x-axis. For example, a B value of -6 would mean that the line crosses the y-axis at (0,-6).

M is your slope. Your slope can be determined by rise/run (how far your line goes up between each point/how far horizontally your line travels between each point). A slope of 2 would mean that the y-values on my line are double the x-values on my line. If a point on the line was (1,2), we could find the slope value by taking 2 and dividing it by 1.

If I had y = 6x+2, my slope would be 6, and my y-intercept would be 2.

Feel free to ask anything is still a little confusing :D

Can someone help me with 4-6 plz
satela [25.4K]

Step-by-step explanation:

4. To use SSS, you need three pairs of congruent sides.  You're given two pairs of congruent sides, so the additional information needed is WY ≅ KM.

5. To use ASA, you need a pair of congruent sides between two pairs of congruent angles.  You're given one pair of congruent angles, and since the triangles share a common side, we know BC ≅ BC.  So the additional information needed is ∠WBC ≅ ∠ACB.

6. To use SAS, you need a pair of congruent angles between two pairs of congruent sides.  You're given two pairs of congruent sides, so the additional information needed is ∠I ≅ ∠F.

Which graph represents a linear function?
pshichka [43]

Answer:

y + 2x = 10 (third option)

Step-by-step explanation:

We can see that every time x increases by one, y increases by -2, meaning that the slope is -2.

We also know that the y-intercept is 10 because that is the value of y when x is equal to 0.

Now, we can create the equation using the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept).

y = -2x + 10

If you look at the third option, that equation is just a rearranged form of our equation (y + 2x = 10).

This means that the third option is correct.
