Question

Write the equations of a line through the point (-3,-8) with a slope of -3/5 in

Answer 1

y=mx+b is the standard function for any straight line

y and x are constants, so they never change in the final form

m is the slope, which is given

b is the y intercept, which is not given

we have to plug in the values to find the solution, so plug in the (x,y) coordinates for their respective places in the equation

-8 = (-3/5)(-3) + b

-8 = 1.8 + b

-9.8 = b

now that we have b, we can just put the slope back in for m and get the answer

y= -3/5x -9.8
