Answer:
y = -1/4x -1
Step-by-step explanation:
Mathematically, we have the slope intercept form as;
y = mx + b
where m is the slope and b is the y-intercept
from the question;
m is -1/4
So we have :
y = -1/4x + b
To get the value of b, we substitute the coordinates given and solve for b
Firstly, multiply through by 4
That will
give ;
4y = -x + 4b
4(-4) = -12 + 4b
-16 = -12 + 4b
-16 + 12 = 4b
4b = -4
b = -4/4
b = -1
So the equation in the slope intercept form is;
y = -1/4x -1
Answer:
M = -2
b = -10
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
m = (-8 -0)/(-1- -5)
= (-8-0)/(-1+5)
= -8/4
= -2
We now want to find the y intercept
y = mx+b is the slope intercept form of the equation
y = -2x+b
Using the point (-5,0)
0 = -2(-5) +b
0 = 10+b
Subtract 10 from each side
-10 = 10-10+b
-10 =b
The y intercept is -10
y= -2x-10
Answer:
=
Step-by-step explanation:
Substitute 3 in for m and solve
4m - 1 = 4(3) - 1 = 11
5m - 4 = 5(3) - 4 = 11
