Start by using the Slope Formula to find the slope.
y=-5/3x+28/3
An equation in slope-intercept form follows a specific format.
y= mx+b
For an equation in this form, m is the slope and b is the y-intercept.
Let's use the given points to calculate m. We will start by substituting the points into the Slope Formula.
Substitute ( 5,1) & ( 8,-4)
A slope of - 53 means that for every 3 horizontal steps in the positive direction, we take 5 vertical steps in the negative direction. Now that we know the slope, we can write a partial version of the equation. y= -5/3 x+b To complete the equation, we also need to determine the y-intercept, b. Since we know that the given points will satisfy the equation, we can substitute one of them into the equation to solve for b. Let's use ( 5, 1).
x= 5, y= 1
a/c* b = a* b/c
LHS+25/3=RHS+25/3
a = 3* a/3

Rearrange equation
A y-intercept of 283 means that the line crosses the y-axis at the point (0,283). We can now complete the equation. y= -5/3x+28/3
