What slope would make the lines
parallel?
y = -3x + 9
y = [?]x + 4

- 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 9 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + 4 ← is the equation of a parallel line

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

may i see the picture? it would a lot, xox
