Answer:
y = -5x -8
Explanation:
Find b in equation y = mx + b
Insert numbers to find b
-3 = -5· -1 + b
Step 1: Simplify both sides of the equation.
−3=(−5)(−1)+b
−3=5+b
−3=b+5
Step 2: Flip the equation.
b+5=−3
Step 3: Subtract 5 from both sides.
b+5−5=−3−5
b=−8
Insert into equation
y = -5x - 8
Answer: y=-5x-8
Let’s start by writing out the model equation for slope-intercept
y=mx+b
M: Slope
X: Variable
B: Y-intercept
Now we know that m is slope. Let’s fill in the slope provided to us, which is -5
y=mx+b
y=-5x+b
Now let’s solve for b. We’ll do this by taking the point given to us and substituting it into the equation and solving.
y=-5x+b
*substitute the y and x of the point*
-3=-5(-1)+b
*multiply -5 and -1*
-3=5+b
*subtract 5 on both sides*
-8=b
Now you know b! Let’s put this into our equation
y=mx+b
y=-5x+b
y=-5x-8
This is your answer! Hope this helps comment below for more questions :)
