Answer:
m= -4/3
b = 1
equation is;
y = -4/3(x) + 1
Explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
From the graph, we can see that the y-intercept is y = 1; so the value of b is 1
We have the equation now as;
y = bx + 1
To get b, we consider a point on the line
The point we are considering is the point (3,-3)
In the incomplete equation, we substitute the coordinates of this point
We have this as;
-3 = m(3) + 1
-3-1 = 3m
3m = -4
m = -4/3
So the equation is;
y = -4/3(x) + 1
