## anonymous one year ago A student has attempted to graph an equation that contains the point (1, -4) and has a slope of 1/3. a. What is the correct equation in slope-intercept form? b. What is the student's error on the graph below?

$y-y_0=m(x-x_0)$ line passes through point (x0,y0) and slope=m

thank you!

4. amoodarya

$y-(-4)=\frac{1}{3}(x-1)$

5. amoodarya

but that line (picture) passes through (1,-4) (2,-1) $m=\frac{\Delta y}{\Delta x}=\frac{y_1-y_0}{x_1-x_0}=\frac{-4-(-1)}{1-2}=+3$ do you get mistake ?

6. anonymous

not really :(

7. amoodarya

you need to write a line ,with slope of 1/3 not 3 !

oooh okay thanks and is y-4=1/3 x- 1 the correct equation?
