Question

The equation of the line shown in the graph is y = ?

Answer 1

Answer:

y = -4x

Step-by-step explanation:

Find the slope (m) and the y-intercept (b) of the line. Thereafter, substitute the value of each into y = mx + b to get the equation of the line.

✔️Find the slope (m) using two points on the line, (-2, 8) and (0, 0):

Slope (m) = change in y/change in x

m = (0 - 8)/(0 - (-2))

m = -8/2

m = -4

✔️Find y-intercept (b):

Y-intercept = 0, this is where the line intercepts the y-axis.

b = 0

✔️Substitute m = -4 and b = 0 into y = mx + b:

y = -4x + 0

y = -4x
