Question

Line JK passes through points J(–4, –5) and K(–6, 3). If the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b?

–21
–4
11
27

Answer 1

Step-by-step explanation:

Given: J (-4,-5) and K(-6,3)

=> x=-4 and y=-5 =>x=-6 and y=3

Solution: now put the value of x and y 8n the same equation ,i.e, y=mx+b

Now for point J the equation will be :

-5= -4m+b or -4m+b=-5 --------------(1)

And for point K the equation will be :

3=-6m+b or -6m+b=3------------------(2)

Now solve equation (1) and (2) by elimination method:
