Question

Write the slope- intercept form of the equation of the line described

through (4,5) parallel to y= 1/4x-4

Answer 1

Explanation:

You get the slope right away, just by reading it.

y = 1/4 x + b

To solve for b, you use the point 4,5

5 = 1/4 * 4 + b Substitute 4 for x

5 = 1 + b Subtract 1 from both sides

5-1 = 1-1 + b

b = 4

The line is y = 1/4 x + 4
