What is the equation in standard form of the line which passes through (4, -2) and has a slope of -3?

Question

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)

$$y=mx+b$$

those 4 equations will pretty much solve all your line related problems, you should memorize them as they will definitely pop up in the future
