Which equation represents the line that passes through the points (-1,-2)and(3,10)

Step-by-step explanation:

(-1,-2) , (3,10)

slope(m) = (10 - (-2) / (3 - (-1) = (10 + 2) / (3 + 1) = 12/4 = 3

y = mx + b

slope(m) = 3

u can use either of ur points

(3,10)x = 3 and y = 10

sub into the formula and find b, the y int

10 = 3(3) + b

10 = 9 + b

10 - 9 = b

1 = b

so ur equation is : y = 3x + 1

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
