Write an equation of the line in slope intercept form

Write An Equation Of The Line In Slope Intercept Form class=

Sagot :

Answer:

a)y=3/2x+6 b) y= -4/3x-2

Step-by-step explanation:

a)using the points given (-2,2) and (0,6)

we use rise over run formula and get 3/2

and we get y intercept by looking at when the line touches the y line in this case 6

using y=mx+b formula when m is slope and b is y interecpt we plug the numbers in

so we get y=3/2x+6

b) For this we use the points given which are (-3,2) and (0,2)

we use the rise over run formula and get 4/3 but since the line is going down it means the slope is negative so we get -4/3

and the y intercept we get by looking at when it touches the y line in this case it touches at -2

so using the same formula as  the first question

but since the y interecpt is negative we change the plus sign for a minus

we get y=-4/3x-2
