1. What is the equation of the line through the points (21, 14) and (49,35)? (Please

be sure to simplify all fractions or write as decimals.)

Pl I need help

3x - 4y - 7 = 0

Step-by-step explanation:

We know that the equation of a straight line passing through two known points and is given by

Therefore, the equation of the straight line passing through the points (21,14) and (49,35) will be

⇒

⇒ 4(y - 35) = 3(x - 49)

⇒ 4y - 140 = 3x - 147

⇒ 3x - 4y - 7 = 0 (Answer)

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !
