Answer:

y = -3x + 1

Step-by-step explanation:

Starting with the point (-1, 4) and the slope m = -3, write out the point-slope equation of a straight line:  y - k = m(x - h) becomes y - 4 = -3(x + 1), or:

y = -3x - 3 + 4

y = -3x + 1    This is the same as answer choice (b).

Rewrite the equation in standard form:<br><br> y = 3/4x - 10
morpeh [17]
<h3>Answer:   3x - 4y = 40</h3>

======================================

Work Shown:

y = (3/4)x - 10

4y = 3x - 40 .... multiply everything by 4 to clear out the fraction

4y+40 = 3x

40 = 3x-4y

3x-4y = 40

This is in the form Ax+By = C

A = 3, B = -4, C = 40

This is not the only solution possible since we can multiply both sides by some number to scale the equation.
