A line passes through( 10, 5) and (13, -4) . Write the equation of the line in standard form

y = -3x - 25

Step-by-step explanation:

Find the slope:

m = ( -4 - 5 ) / ( 13 - 10 )

m = -9 / 3 = -3

pick one point and substitute it in the standard equation

y - y1 = m ( x - x1 )

y - 5 = -3 ( x - 10 )

y - 5 = -3x - 30

y = -3x - 25

m = -3,  b = -25

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
