Answer:
y = 9x/2 + 17/2
Step-by-step explanation:
Use the slope formula: to find the slope of the line.
(4 - (-5)) / (-1 - (-3)) = (4 + 5) / (-1 + 3) = 9 / 2
y = mx + b
m is for slope, b = y-intercept
y = 9x/2 + b
Plug in one pair of the known values:
(-1,4)
4 = 9(-1)/2 + b
b = 4 + 9/2 = (8+9)/2 = 17/2
y = 9x/2 + 17/2
If you want to check if the equation is right, you can plug in the other pair of values into the equation:
(-3,-5), y = 9x/2 + 17/2
-5 = -3*9/2 + 17/2
-5 = -27/2 + 17/2
-5 = -10/2
-5 = -5
