I need help with this

make a table with an x and y column then input different x values. For each x value, plug into the equation and solve for y. For the graphing, 4 is the slope and 2 is the y-intercept. So, from the y intercept, go up four and over one and repeat. For the other end of the graph go down 4 and left one to fill out the graph
Make a quick table.
x = - 2
y = 4 ∙ ( - 2 ) + 2 = - 8 + 2 = - 6
x = -1
y = 4 ∙ ( - 1 ) + 2 = - 4 + 2 = - 2
x = 0
y = 4 ∙ 0 + 2 = 0 + 2 = 2
x = 1
y = 4 ∙ 1 + 2 = 4 + 2 = 6
x = 2
y = 4 ∙ 2 + 2 = 8 + 2 = 10
For graph find x - intercept and y - intercept.
The point where the line crosses the x - axis is called the x - intercept.
The y - intercept is the point where the line crosses the y-axis.
This mean:
x - intercept is point where y = 0
y - intercept is point where x = 0
x - intercept:
y = 0
y = 4 x + 2 = 0
Subtract 2 to both sides
4 x + 2 - 2 = 0 - 2
4 x = - 2
Divide both sides by 4
x = - 2 / 4 = - 1 ∙ 2 / 2 ∙ 2 = - 1 / 2
Coordinates of x - intercept:
x = - 1 / 2 , y = 0
You can write coordinates like ( - 1 / 2 , 0 )
y - intercept:
x = 0
y = 4 ∙ 0 + 2 = 0 + 2 = 2
Coordinates o y - intercept:
x = 0 , y = 2
You can write coordinates like ( 0 , 2 )
Now draw the straigh line through these two points.
x = - 2
y = 4 ∙ ( - 2 ) + 2 = - 8 + 2 = - 6
x = -1
y = 4 ∙ ( - 1 ) + 2 = - 4 + 2 = - 2
x = 0
y = 4 ∙ 0 + 2 = 0 + 2 = 2
x = 1
y = 4 ∙ 1 + 2 = 4 + 2 = 6
x = 2
y = 4 ∙ 2 + 2 = 8 + 2 = 10

y - intercept is point where x = 0
x - intercept:
y = 0
y = 4 x + 2 = 0
Subtract 2 to both sides
4 x + 2 - 2 = 0 - 2
4 x = - 2
Divide both sides by 4
x = - 2 / 4 = - 1 ∙ 2 / 2 ∙ 2 = - 1 / 2
Coordinates of x - intercept:
x = - 1 / 2 , y = 0

Thank you very much, now I understand it.
so what is the answer im confused

are they right
no
yo this is just chaos what's the answer-
complete the function table. then write a rule for the function
I'm sorry, I didn't see the original question! What is the function table you would like me to complete? Once we have the table completed, we can write a rule for the function.
write an inequality to represent the situation: the temperature stayed above -15
The inequality to represent the situation "the temperature stayed above -15" is:
T > -15
Where T represents the temperature. The greater than symbol (>), means that the temperature is greater than -15 which implies that the temperature stayed above -15.
T > -15
Where T represents the temperature. The greater than symbol (>), means that the temperature is greater than -15 which implies that the temperature stayed above -15.
