Choosing points (0;5) and (-2;-3) so we have
X = 0, Y = 5
X = -2, Y = -3
Equation: Y = aX + b
Using point 1:
5 = a0 + b
=> b = 5
Then again
Y = aX + b
-3 = a(-2) + 5
-3 - 5 = -2a
- 8 = -2a
=> a = 4
Y = 4X + 5
X = 0, Y = 5
X = -2, Y = -3
Equation: Y = aX + b
Using point 1:
5 = a0 + b
=> b = 5
Then again
Y = aX + b
-3 = a(-2) + 5
-3 - 5 = -2a
- 8 = -2a
=> a = 4
Y = 4X + 5
Answer:
y=4x+5
Step-by-step explanation:
Liner graph, therefore, y=mx+b; b is the y intercept; m is the slope
b=5, another pair is (-1,1)
need to find m first
Substituting we get:
⇒1= m(-1) + 5
⇒1= -1m + 5
⇒1-5= -m
⇒-4 = -m
⇒m=4
Eq: y=4x+5
