Answer:
(5, 2)
Step-by-step explanation:
Lets substitute y = -x + 7 into 4x-5y=10
Then we can write 4x-5y=10 as 4x-5×(-x+7)=10,
4x-(-5x)-35=10
9x-35=10
9x=45
x=5, therefore, y= -5+7=2

Answer:
y = (7/9)x
Step-by-step explanation:
The equation of a straight line is given as y = mx + b, where y and x are variables, m is the rate of change = change in y / change in x, while b is the y intercept (value of y when x = 0).
When no pint is used, there is no frozen yoghurt. But from 9 pints, 7 large servings of frozen yogurt is made. Let x represent the number of pints and the y represent the number of servings.
Hence, using y = mx + b, we get b = 0, because at 0 pint there is no servings. The equation be comes y = mx
m = change in y / change in x = 7 servings / 9 pints
m = 7/9
The equation is:
y = (7/9)x
