Plzzz help super easy and I'm running out of time!!!

Answer:

y = 2x -5

Step-by-step explanation:

Given points: (0,-5) (1,-3)

(x1, y1) = (0,-5)

(x2, y2) = (1,-3)

Calculate the slope:

m = (y2 - y1)/(x2 - x1)

m = [-3 - (-5)] / [1 - 0]

m = (-3 + 5) / 1

m = 2/1 = 2

Next, the y-intercept is the value of y when x = 0. One of your given points is the y-intercept, (0, -5). The y-coordinate is the value of b.

Therefore, the linear equation is: y = 2x -5
