Question

I THINK IT"S "D"

What is the slope-intercept form equation of the line that passes through (2, 4) and (4, 10)?

y = −3x − 2

y = −3x + 2

y = 3x + 2

y = 3x − 2

Answer 1

Slope m=(y2-y1)/(x2-x1)=(10-4)/(4-2)=6/2=3

y = mx+b
y=3x+b
Take point (2,4),
4=3*2+b
4=6+b
b=-2
y=3x-2
Answer is D. y = 3x − 2
