Line t passes through points (10, 4) and (7, 9). Line u is parallel to line t. What is the slope of line u?

3/5

Step-by-step explanation:

concept to know: the slope of perpendicular line is always opposite reciprocal

Step 1. Find the slope of line t

 (y2-y1)/(x2-x1)

=(4-9)/(10-7)

=-5/3

Step 2. Apply the concept

Opposite reciprocal of (-5/3)=3/5

Hope this helps!! :)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
