Question

Find the slope and y-intercept of equation 19x - 4y = 7

Answer 1

Slope: 19/4

y-intercept: 1.75

Explanation:

19x-4y=7

To find the slope and y-intercept, change the order of the equation to put it in y-intercept form. (y-intercept form: y=mx+b). Where m equals slope and b is the y-intercept.

In order to do this, Subtract 19x from both sides of the equation to equal:

• -4y=7-19x

This equation can also equal out to:

• -4y=-19x+7

Now, divide each side by -4

• y=
  `(19)/(4)`x-1.75

This will mean that 19/4 is the slope and 1.75 is the y-intercept
