Answer:

standard form:  -4x + y = 4

slop-intercept form:  y = 4x + 4

Step-by-step explanation:

Find two points on the line:  (0, 4) and (-1, 0)

slope = change in y ÷ change in x = (4 - 0) ÷ (0 - -1) = 4 ÷ 1 = 4

from inspection, y-intercept = 4

Therefore, equation of line in slope-intercept form:  y = 4x + 4

Now use this to determine standard form

Standard form: Ax+By=C

so for  y = 4x + 4

standard form is:  -4x + y = 4
