Write the equation of the line that has a slope of 3 and contains the point (1.4)​

Sagot :

Answer:

  • These are the two methods to finding the equation of a line when given a point and the slope:

Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. ...

Point-slope form = y − y 1 = m ( x − x 1 ) , where ( x 1 , y 1 ) is the point given and m is the slope given

  • Slope-intercept form is y = mx + b. In this equation, m is our slope and b is our y-intercept. The prompt gives us a slope of 3, and the point (0,3) is a y-intercept at 3. Using this, we just have to plug it into our equation: y = 3x + 3.
