What is the point-slope form of a line that has of 1/2 and passes through point (-7,2)?

y = 1/2 x + 5.5

Step-by-step explanation:

Given the slope and one ordered pair, you can plug in the x and y values from the pair into the formula "y = mx + b" to determine b, which is the y-intercept.

In this case, -7 is the x value, and 2 is the y value.

2 = 1/2 (-7) + b

2 = -7/2 + b

Convert -7/2 to a decimal to get -3.5

2 = -3.5 + b

add 3.5 to both sides to isolate b

5.5 = b

Now that you have the y-intercept, you can write the equation in the new form:

y = 1/2 x + 5.5

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

true? is that what you're asking or do you mean something else?
