35. Write an equation in point-slope form for the line through the given point with the given slope. (–7, 9); m = (1 point)

y + 7 = (x – 9)
y – 7 = (x + 9)
y – 9 = (x + 7)
y + 9 = (x – 7)

Question

35.   Write an equation in point-slope form for the line through the given point with the given slope. (–7, 9); m =  (1 point)

y + 7 = (x – 9)
y – 7 = (x + 9)
y – 9 = (x + 7)
y + 9 = (x – 7)

IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
$$m=\frac{y_2-y_1}{x_2-x_1}$$

standard formula
$$Ax+By=C$$

point-slope formula
$$y-y_1=m(x-x_1)$$

slope-intercept formula
b= y-intercept -- in the form of (0,y)

$$y=mx+b$$

yeah look at what completeidiot posted. Look at slope definition as a good basis for point-slope
