Answer 1

D

Step-by-step explanation:

m = 3/4

point: (-4, 1)

We can use the slope-intercept form. We know one point, so we can use its coordinates for x and y. We also know the slope, so we use the slope for m. Then we solve for b.

y = mx + b

Substitute m with the slope.

y = (3/4)x + b

Use the x-coordinate of the given point for x and the y-coordinate of the given point for y.

1 = (3/4)(-4) + b

Solve for b.

1 = -3 + b

b = 4

Now that we know the value of b, we can write the equation of the line.

y = mx + b; m = 3/4; b = 4

y = 3/4 x + 4

Answer: D

Answer 2

Answer: Choice D

Step-by-step explanation:

I'll use the point-slope form to get the following

`y - y_1 = m(x - x_1)\\\\y - 1 = (3)/(4)(x - (-4))\\\\y - 1 = (3)/(4)(x + 4)\\\\y - 1 = (3)/(4)x + (3)/(4)*4\\\\y - 1 = (3)/(4)x + 3\\\\y = (3)/(4)x + 3 + 1\\\\y = (3)/(4)x + 4 \ \ \text{... matches with choice D}\\\\`

You should find that plugging x = -4 into equation D will lead to y = 1 as a way to confirm the answer.
