Answer:

Step-by-step explanation:
slope-intercept form: y = mx + b
Given:
Slope(m) = 
Point = (-1, 3)
To write the equation in slope-intercept form we need to know the slope(m) and the y-intercept(b). Since we already know the value of m, we can use it and the given point to find b:



Now that we know the values of b and m, we can write the equation:

7 because 42 divided by 6= 7 and length times width = perimeter
Soz man i use the metric system
Answer:
nth term = 7n - 2
Step-by-step explanation:
a = first term = 5
d = common difference = second term - first term
= 12 - 5 =7
d = 7
a + (n-1)d
= 5 + (n -1)7
= 5 + 7n - 7 {add like terms}
= 7n - 2
