Answer:
y = -2x + 6
Explanation:
Slope-intercept form: y = mx + b
Given:
Slope(m): -2
Point: (-1, 8)
To write the equation in slope-intercept form we need to find the slope(m) and the y-intercept(b).
Since we already know the slope is -2, we can move on to finding the y-intercept. To find the y-intercept, input the values of the slope and the point into the equation format and solve for b:
y = mx + b
8 = -2(-1) + b
8 = 2 + b
6 = b
The y-intercept is 6.
Now that we know the slope and the y-intercept, we can write the equation:
y = -2x + 6
