Answer:
y=x+2
Step-by-step explanation:
Given, m = 1
Eqn of st line is y = mx + c
y = 1*x + c
y= x + c ........eqn (i)
since, the line passes through the point (4,2)
4 = 2 + c
c = 4 - 2
c = 2
Now, Putting the value of c = 2 in eqn (i)
y = x + 2 is req eqn of line
Answer:
Question #3: Answer = 31
Step-by-step explanation
• Plug in 3 for x
• Plug in -4 for y
| -3(3)² + 2(-4) | -(3)(-4)
From here, simplify. Don't forget to use PEMDAS!
| -27 +8 | + 12
| -19 | + 12
19 + 12
31
Use this same method to solve for Question #2!
