padilas [110]

Answer:

Part 1) y=-4x+4

Part 2) The graph in the attached figure

Step-by-step explanation:

Part 1)

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

m=-4\\point\ (2,-4)

substitute in the linear equation

-4=-4(2)+b

solve for b

-4=-8+b\\b=8-4\\b=4

substitute

y=-4x+4

Part 2) Draw the equation

we know that

To graph a line we need two points

we have the y-intercept (0,4) and (2,-4)

Plot the points, connect them and join to draw the line

see the attached figure
