Plz i really need to get this right

y = 2x

Step-by-step explanation:

Note the relationship between x and y, that is

x = - 42 → y = - 84 ← that is y = 2x

x = - 14 → y = - 28 ← that is y = 2x

x = 14 → y = 28 ← that is y = 2x

x = 42 → y = 84 ← that is y = 2x

Thus the linear equation is y = 2x

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

The formula of a slope:

From the table we have the points (14, 28) and (42, 84).

Substitute:

Put the val;ue of a slope and the coordinates of the point (14, 28) to the equation of a line:

   subtract 28 from both sides

Finally we have:
