Answer:

A. y = 3x-1; slope is 3 and y-intercept is -1

B. -x+3 = y; slope is -1 and y-intercept is 3

C. x-3 = y; slope is 1 and y-intercept is -3

D. y = 1-3x; slope is -3 and y-intercept is 1

Step-by-step explanation: woof

Answer:

1) Slope = -1, y-intercept = 3

2) Slope = 1, y-intercept = -3

3) Slope = -3, y-intercept = 1

4) Slope = 3, y-intercept = -1

Explanation:

In order to identify slope and y-intercept, you must find where each variable hits each axis when the other is 0.

For example, to find the y intercept of y=2x-4, you would substitute 0 in for x and solve for y.

y = 2(0)-4 --> y = -4

Thus, the point is (0, -4) with slope of 2. (The slope can be found by identifying the number, m, in front of 'x' from the equation y = mx + b.
