This table gives a few (x, y) pairs of a line in the coordinate plane.
X. Y
(34 (-52)
(51) (-65)
(68) (-78)
What is the y-intercept of the line?

Respuesta :

Answer:

c=180 (aka the y-intercept)

Step-by-step explanation:

y=mx+c

first find m

m= change in y/change in x

pick two random ones for example

(34 (-52)

(51) (-65)

do (-52-65)/(34-51)=m

m=-6.88............

so now we have

y=-6.88x+c

lets take the first coordinate and plug it in to the formula

(34 (-52)

-52=-6.88x34+c

solve equation to find c

-52=-234+c

180=c
