Heather was asked to graph 3x - y = -4 by using slope and y-intercept. her graph is shown. which choice supports the graph that she has drawn? a) the slope is positive 3 and the y-intercept is (0, 4). b) the slope is negative 3 and the y-intercept is (0, 4). c) the slope is positive 3 and the y-intercept is (0, -4). d) the slope is negative 3 and the y-intercept is (0, -4).

A) The slope is positive 3 and the y-intercept is (0, 4).

Step-by-step explanation:

3x - y = -4

-3x-3x

-y = -3x - 4

__

-1-1

y = 3x + 4 >> y-intercept at [0, 4] and has a positive three rate of change [slope] ☑

I am joyous to assist you anytime.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
