Answer:
The equation of the line will be:
Step-by-step explanation:
Given the points
Finding the slope
We know that the value of y-intercept can be obtained by setting x=0, and solving for y
Here,
at x = 0, the value of y = 0
Thus,
y-intercept = b = 0
We know the slope-intercept form of the line equation is
where m is the slope and b is the y-intercept
now substituting m = 0 and b = 0 in the slope-intercept form
y = mx+b
y = 0(x) + (0)
y = 0+0
y = 0
Therefore, the equation of line will be:
Answer:
x + 27 = - 12
x = - 39
Step-by-step explanation:
I think that the answe my be b
Answer:
A7.45x = y
Step-by-step explanation:
We can use a ratio to solve this problem. Take the total cost of the lunches and divide by the number of lunches.
y = total cost of lunches and
x = number of lunches
74.50 y
-------------- = ------------
10 x
Using cross products
74.5 x = 10 y
Divide each side by 10
74.5/10 x= 10y/10
7.45x = y
