Question

Write the equation of the line in slope-intercept form that has a slope of y and passes through the point (4,3). Write the equation in slope-intercept form of the line that has a slope of 2 and passes through the point (-1,1).

Answer 1

y = 2x + 3

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 = 2 , then

y = 2x + c ← is the partial equation

to find c , substitute the point (- 1, 1 ) into the partial equation

1 = 2(- 1) + c = - 2 + c ( add 2 to both sides )

3 = c

y = 2x + 3 ← equation of line
