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 = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
