Answer:
y = -x + 4
Step-by-step explanation:
Slope-intercept form of a line is the equation: y = mx + b
where m is the slope and b is the y-intercept
Step 1: Find the slope
Label the points that are given.
(-1,5) = (x1, y1)
(0, 4) = (x2, y2) (this is what they told us the y-intercept is)
The formula for slope is: m = (y2 - y1)/(x2 - x1)
The slope for this problem is
m = (4 - 5)/(0 - (-1))
m = -1/1 = -1
We now have m and b, so our equation is: y = -x + 4
