A linear relationship with a slope of 2 and a<br> y-intercept of 3
qwelly [4]

Answer:

The linear relationship is represented by y = 2x + 3.

Step-by-step explanation:

We are given a y-intercept of an equation as well as a slope:

  • slope = 2
  • y-intercept = 3

We can use this information and substitute it into the slope-intercept form equation to get our linear relationship:

  • y = mx + b

In this formula, m is our slope and b is our y-intercept.

Therefore:

  • m = 2
  • b = 3

Finally, let us substitute these into the equation:

  • y = 2x + 3

This is our final equation.

Find the equation of the line through point (3,2) and perpendicular to 3x + 5y = 15
Vesnalui [34]

Answer:

y=5/3x-3

Step-by-step explanation:

first, let's put 3x+5y=15 into y=mx+b form

move 3x to the other side

5y=-3x+15

divide by 5

y=-3/5x+3

now, perendicular lines have slopes that are negative and reciprocal.

With our new equation we can automatically find the slope, which would be 5/3.

now, we need to find b

plug the points (3,2) into y=5/3x+b

2=5/3(3)+b

2=5+b

-3=b

so that means that our equation will now be

y=5/3x-3.

Hope this helps!
