Question

Write an equation of a line with slope -3 ans y-int (0,5) Equation:

Answer 1

Answer: y = -3x + 5

Explanation:

When we have the slope and the y-intercept, we can use the slope-intercept formula to find the y-intercept.

We know that the line passes through (0,5) and has a slope of -3.

The slope-intercept formula:

`\bf{y=mx+b}`

where:

• m => slope
• b => y-intercept

We need the value of b. Given the point (0,5) we see that the value of b is 5.

So we put in the values :

• 
  `\bf{y=-3x+5}`

Answer 2

y = - 3x + 5

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given slope m = - 3 and y- intercept is (0, 5 ) , so c = 5

y = - 3x + 5 ← equation of line
