Y = mx + b. This linear graph passes through A(0,50) and B(10,51)
m = (y₂-y₁)/(x₂-x₁)
m= (51-50)/10-0)
m=(1)(10)
y = (1/x) + b. To find b, you plugin the coordinates of either A or B,
say A(0,50):
50 = (1/10).(0) + b
50 = 0+b and b= 51
Hence the equation is y =0.1x + 50
I need to answer so i can ask a question
Answer:
The y-intercept of the line is 9.
Step-by-step explanation:
y-y1=m(x-x1)
y-1=-2(x-4)
y-1=-2x+8
y=-2x+8+1
y=-2x+9
y=mx+b where m=slope and b=y-intercept
