Question

Complete the slope-intercept form of this line. y=-4x +

Answer 1

Answer:

It is y = -4x + 9

Step-by-step explanation:

General equation of a line:

$y = mx + c$

For a y-intercept, c :

consider point (2, 1):

y is 1, x is 2 and m is -4

$y = mx + c \\ 1 = (2 \times - 4) + c \\ 1 = - 8 + c \\ c = 1 + 8 \\ c = 9$

therefore, equation is:

$y = - 4x + 9$
