Question 302039
general slope-intercept is ___ y = mx + b ___ where "m" is the slope and "b" is the y-intercept
___ the y-intercept is the value of "y" where the line crosses the y-axis ("x" is zero at this point)


start by finding the slope ___ the change in "y", divided by, the change in "x"


m = (4 - 0) / (7 - -2) = 4/9


use the general equation, and substitute one of the points to find "b"


y = (4/9)x + b ___ 4 = (4/9)7 + b ___ 4 = (28/9) + b ___ 8/9 = b


so the slope-intercept equation is ___ y = (4/9)x + (8/9)
