Question

Using the given sets of points, identify slope (m), y-intercept (b), and write the equation. (0, 4) and (-1, -1)

Answer 1

Answer:

y = 5x + 4

Step-by-step explanation:

Its a given that the y intercept is 4 because on that point x = 0

B= 4

now you solve for your slope using y - y' / x - x'

when you plug in the numbers you get -1 - 4 / -1 - 0 which simplfies to -5 / -1 which simplifies just to 5, so we know the slope is = 5

now we just plug In and the base equation is y = mx + b.
