Find the equation of the line using the slope formula. write the final equation using the slope-intercept form. the x- intercept is 1, and (x, y) = ( -2, 12) is a point on the line

Step-by-step explanation:

The slope formula for a straight line is:

Where, 'm' is the slope and 'b' is the y-intercept.

To find the x-intercept of a line, we need to equal 'y' to zero, and then solve for 'x'. In this case we know that the x-intercept is 1, so we have the point (x1, y1)=(1,0). We are given a second point which is: (x0, y0)=(-2, 12).

To find the slope, we use the following formula:

Now, The equation of the line is: y - y0 = m(x-x0). Then, substituting the values of 'm', 'x0' and 'y0' we have that:

The equation of the line using the slope-intercept form is:
