Question

14. Write an equation for the line through the point P(4, 7) with a slope of -3 in slope-intercept form.

Answer 1

An equation of a line through a point P(x1 , y1) with slope m is given by
y-y1=m(x-x1)
Point (4,7), then x1=4 and y1=7

The slope is m=-3
y-7=-3(x-(4))
y-7=-3(x-4)
y=-3x+12+7
y=-3x-19 the equation of a line
