5y = X
y = X/5
y = 1/5 X + 0
So the y-intercept is 0, meaning that both intercepts are the same, at (0,0). However, there is a slope in the equation (1/5), meaning the rise is 1, and the run is 5, so the next point on the line is (5, 1), and then (10,2), and so on. Hope this helps!

Five times the difference of a number n and forty two is ten more than twice the product of a number x and number y
- Five times: 5 ×
- difference of a number n and forty two: (n - 42)
- is: =
- twice the product of a number x and a number y: 2(xy)
- ten more than: + 10
Rewrite the expression into an equation.
5(n - 42) = 2(xy) + 10

For this case we have that the slope of a line is given by:
If we have the points:
Thus, the equation is of the form:
Substituting any of the points we have:
Answer:
Option D
Answer:
Choice D is the answer.
Step-by-step explanation:
We have given two points.
Let (x₁,y₁) = (-1,4) and (x₂,y₂) = (8,-2)
We have to find the point-slope form of the line that passes through the given points.
y-y₁ = m(x-x₁) is point-slope form of the line that passes through the points.
m is slope of line.
m = y₂-y₁ / x₂-x₁
Putting values in above formula , we have
m = -2-4 / 8-(-1)
m = -6 / 9
m = -2/3
Putting values of slope and using a point , we have
y-4 = -2/3(x-(-1))
y-4 = -2/3(x+1) is point-slope form of line that passes through the points (-1,4) and (8,-2).
