the equation of the straight line that passes through the point with coordinates of 0,0 and 2,8. do the same for the coordinates of 0,0 and 4,20,0 and 2,10

Equation of a line passes through (0,0) and (2,8):

Equation of a line passes through (0,0) and (4,2):

Equation of a line passes through (0,0) and (2,10):

Step-by-step explanation:

Equation of a line passes through (a,b) and (c,d) :

Then, Equation of a line passes through (0,0) and (2,8):

Equation of a line passes through (0,0) and (4,2):

Equation of a line passes through (0,0) and (2,10):

i do not know this sorry : (

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
