Answer:

a) 3

Step-by-step explanation:

Use the nth tern equation of the AP

$a_n=a_1+(n-1)d$

We have

$a_1=-2$ and $a_{10}=25$

Find the value of d

25 = - 2 + (10 - 1)d
25 + 2 = 9d
27 = 9d
d = 27/9
d = 3

Correct choice is a)

What is the equation of the line that passes through (0, -2) and has a slope of O?

Dmitriy789 [7]

Answer:

The equation of the line that passes through (0, -2) and has a slope of 0 is $\mathbf{y=-2}$

Step-by-step explanation:

We need to find the equation of the line that passes through (0, -2) and has a slope of 0?

The equation of line can be expressed in slope-intercept form $y=mx+b$ where

m is slope
b is y-intercept

We need to find slope and y-intercept for the equation.

We are given slope = 0 so, m = 0

Now, y-intercept can be found using slope m=0 and point (0,-2)

$y=mx+b\\-2=0(0)+b\\-2=b\\or\\b=-2$

So, we get y-intercept: b = -2

Now, the equation of the line having slope m=0 and y-intercept b=-2 is:

$y=mx+b\\y=0(x)-2\\y=-2$

So, the equation of the line that passes through (0, -2) and has a slope of 0 is $\mathbf{y=-2}$
