Find delta y/delta x
(10-7)/(15-12)=3/3=1, (15-10)/(20-15)=5/5=1
y=x+b, using any point, I'll use (20,15) we can solve for b...
15=20+b
b=-5 so our line is:
y=x-5, and we want to know when y=17
17=x-5
x=22
so n=22
Answer:
x + 3y = 15
Step-by-step explanation:
Line is passing through the points
Slope of line (m)= (2 - 4)/(9 - 3) = -2/6 = -1/3
Equation of line in point-slope form is given as:
Plugging the values of in the above equation we find:
This is the required equation of line in the form
43 is between the 40 and 45
Answer:
7n - 2 = 19
Step-by-step explanation:
7 times a number is 7n.
7 times a number, decreased by 2, is 7n - 2.
7 times a number, decreased by 2, is 19 is represented by 7n - 2 = 19
