What is an equation of the line that passes through the points (8,-1) and (4,-1)?pleaseee i need helppp

y = -1

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept.

First, find the slope by doing change in y / change in x:

-1 - (-1) / 8 - 4  = 0 / 4 = 0

this means that m = 0, so the equation so far is y = 0x + b or y = b

Then, you need to find what b is and since you know x = 8 and y = -1 is a solution, you can plug that into the equation:

-1 = 0 * 8 + b

-1 = b

This means that b = -1 and the equation would be y = -1

y=-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-1))/(4-8)

m=(-1+1)/-4=0/-4=0

slope is 0

y-y1=m(x-x1)

y-(-1)=0(x-8)

y+1=0

y=0-1=-1

y=-1

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.
