Use the two given points to find the line, in any form.
Trying formula for slope, m=(2--4)/(-1--10), m=6/9, m=2/3.
Try now point-slope form. y-2=(2/3)(x-(-1)),

Convert the equation to slope intercept form.
y-2=(2/3)(x+1)
y=(2/3)x+2/3+2

Read the value for the y intercept directly from the equation.
y=mx+b common general formula for slope-intercept form equation for a line, so b=?
