Question

What is the y-intercept of a line that has a slope of 1/4 and passes through point 8,3

Answer 1

• m=1/4
• (8,3)

Slope intercept form

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto 3=\dfrac{8}{4}+b$

$\\ \sf\longmapsto b+2=3$

$\\ \sf\longmapsto b=3-2=1$

Answer 2

Y=Mx+b
Add the slope and points
3=(1/4•8)+b
Solve for be
3=2+b
1=b
Your y-Intercept is one
