Complete the point-slope equation of the line through (-5,7) and (-4,0)
solve this: y -- 7= ___
please help
+981 Point-Slope form is:
y - b = m(x - a)
Where m is the slope, and (a,b) is a point the line passes through.
Since we are already given the points, we can plug them in to update our equation:
y - 7 = m(x - (-5))
Simplyfied:
y - 7 = m(x + 5)
We now need to solve for the slope.
The slope is rise over run.
Rise is the first y value minus the second y value.
Run is the first x value minus the second x value
Rise is 7 - 0 = 7
Run is -5 - ( -4 ) = -1
The slope is -7.
The equation in point-slope form is y - 7 = -7(x + 5)
