Umnica [9.8K]

Step-by-step explanation:

we see 2 confirmed points with whole integers as coordinates.

(-2, -1) and (1, 2)

the general equation for a line is

y = ax + b

a is the slope expressed as y/x ratio indicating how many units y changes , when x changes for a certain amount of units when going from one point to another.

so, when going from (-2, -1) to (1, 2)

x changes by +3 units (from -2 to 1)

y changes by +3 units (from -1 to 2)

so, the slope (a) is 3/3 = 1

b is the y-intercept (the y value when x=0, so, the point where the line crosses the y-axis).

our equation looks now like this

y = x + b

to get b we use the coordinates of one of the points as x and y. e.g. (1, 2) :

2 = 1 + b

b = 1

the full equation is

y = x + 1

Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.
Irina18 [472]
A=first term
n=number of terms
d=common difference

Formula: a+(n-1)d
10th term;
a=-10
n=10
d=-2

-10+(10-1)-2
-10+(9)-2
-10+-18
-10-18
10th term= -28

A.P= -10,-12,-14,-16,-18,-20,-22,-24,-26,-28,...
