Answer:

1. Slope: -0.75x or -3/4x

Y-intercept: 7

Equation: -0.75x+7 or -3/4x-7

Remember -0.75 and -3/4 are the same!

2. Equation: 0.5x-3 or 1/2x-3

I used slope intercept form to solve. (y2-y1 over x2-x1) If you need more help comment below or send me a link!

Answer: (1) -3/4   (2) 7     (3) y = (-3/4)x + 7     (4) 1/2

Step-by-step explanation:

1) COUNT the number of spaces from one point to the other point.

   from (0, 7) to (4, 4) is: down 3 and right 4   →   m = -3/4

2) the y-intercept is where the line crosses the y-axis (when x = 0).

   The line crosses the y-axis at (0, 7)    →   b = 7    

3) Slope-Intercept form is y = mx + b

   m = -3/4  and b = 7     →      y = (-3/4)x + 7

4)  COUNT the number of spaces from one point to the other point.

 from (-2, -4) to (2, -2) is: up 2 and right 4   →   m = 2/4  = 1/2 when simplified
