Question

Write an equation of the line with the given slope and y-intercept

1. slope: 1, y-intercept: 10 4
a. y=−3x+10 c. y=x+10 b. y=x–10 d. y=–x+10

Answer 1

The equation of line is y = x + 10

Explanation:

Given as :

The slope of line = m = 1

The y intercept of line is 10

Now equation of line in intercept form is y = m x + c

∵ The line have y intercept only then x axis of line is zero

So, The equation of line

10 = 1 × 0 + c

Or, 10 = 0 + c

So, c = 10

∴ The new equation of line become y = 1 × x + 10

I,,e y = x + 10

Hence The equation of line is y = x + 10 Answer
