Write a slope-intercept equation for a line that passes through (-3,1) and (3, - 11).

Write A Slopeintercept Equation For A Line That Passes Through 31 And 3 11 class=

Sagot :

Answer:

look below

Step-by-step explanation:

Slope intercept is y=mx+b

first we need to do this

-11 - 1

--------

3 - (-)3

a negative - a negative is just adding so really its

-11 - 1

-----------

3 + 3

this gets you -12/6

-12/6 is -2 which means are slope is -2

now we have

y=2x+b but now we need to find b

We replace y with a y from the prob and the x with an x for the problem

so lets use -3,1

so now we have

1 = 2(-3) + b

2x-3 is -6

We need to get to one so we need to do + 7 which means b = 7

so the equation is y=2x+7
