Slope-intercept equation:

y = mx + c

m = slope

c = y-intercept

y = - 3x + 31

Answer:


y=-3x+31

Explanation:

the general form of the slope-intercept equation is as follows:


y=mx+b

where
m is the slope of the line, and
b is the y-intercept.

In this case we know that the slope is:


m=-3

and the y-intercept is the value of
y when
x=0, from the given point the y-intercept is at (0, 31) so the value of y, when
x=0 is
31, thus:


b=31

and we substitute this values in the general form of the equation:


y=mx+b\\y=-3x+31

the slope intercept equation is
y=-3x+31
