Question

Can anyone help me get this last part?

Answer 1

Explanation:

substitute a point value into the equation to find the missing number (the y-intercept)

you could either substitute (0,-4) or (1,2) into the equationn

y = 6x + b

-4 = 6(0) +b

-4 = 0+b

b = -4

or

y = 6x +b

2 = 6(1) + b

2= 6 +b

b= -4

Answer 2

-4

Explanation:

Y = mx+b is the slope intercept form of the equation

where m is the slope and b is the y intercept

The y intercept is where the line crosses the y axis

It is the value where x is zero

(0,-4) the x value is zero so the y intercept is -4
