Question 1018750
y - 4 = 2(x - 1)
:
: we first arrange this equation into the slope - intercept form
:
: add 4 to both sides of =
y = 2(x - 1) + 4
: now multiply the terms within parenthesis by 2
y = 2x -2 +4
: combine like terms
y = 2x + 2
: this form tells us that the slope(m) of the line is 2 and that the line intercepts the y axis at (0, 2)
:
