Answer:
y-11 = -x + 14
Step-by-step explanation:
The quickest way to a proper equation here is to use the point-slope form:
y-k = m(x-h). Here x = 14 and y = 11, so:
y-11 = -1(x-14), or y-11 = -x + 14.
In slope-intercept form, that'd be y = -x + 25.
Answer:
The sum of all four integers is 60.
Step-by-step explanation:
Let the integers be x, x + 2, x + 4, and x + 6.
x + x + 6 = 30
2x = 24
x = 12
So x + x + 2 + x + 4 + x + 6 = 4x + 12 = 60
