Question

Slope intercept form of the equation of the line through the given points Through: (-4,3),(4,5)

Answer 1

Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4

slope=1/4

y=mx+b
m=slope
b=yint
solve for yint
input a point

(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b

y=1/4x+4
