4+1, 3+2, 2+3, 1+4. 4 total combinations, unless 4+1 and 1+4 are the same. In that case, there are only 2, 1+4, and 2+3
Answer:
7 is your answer
Step-by-step explanation:
Note the slope-intercept form:
y = slope(x) + y-intercept (or y = mx + b)
b is the y-intercept.
In this case, 7 is in the place of b, so 7 is your answer

Answer:
y=-2x+7
enter the point into point slope form to find the slope and then use one of the points in point slope form and rearrange it to have y by itself
To solve this problem you must apply the proccedure shown below:
You must switch the variables, and then, you must solve for 
, as following:
Therefore, as you can see, the answer is:
