Answer:
1. Slope: -3; passes through (0,5)
y = mx + b
5 = -3(0) + b
5 = b
y = -3x + 5
2. Passes through (0, -2) and (4,-1)
m = -1 + 2 / 4 - 0
m = 1/4
y = mx + b
-2 = 1/4(0) + b
-2 = b
y = 1/4x - 2
Step-by-step explanation:
Part 1
1. write down the slope intercept formula
2. replace x and y by their value
3. solve for b
4. write your answer by putting them in the formula again
Part 2.
1. label your ordered pairs and write down the slope formula
2. solve for the slope by replacing the letters by their values
3. choose any one of the pairs, write down the slope intercept form formula and replace the letters by their values.
4. solve for b, and then put your answers back into the formula.
