Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8
See the table below for the missing values.
The mistake made by student is 6x(3) = 18x
because 18x + 6x = (18+6) x = 24x
(0,2) because following the formula x,y, the 2 is the y, while the 0 is the x.
