How do you find the slope-intercept form for the equation of the line which passes through the point (5, 2) and which has a y-intercept of 7?
The equation of a straight line is written in the form
We need to have values for the slope (m) and the y-intercept (c).
We do have a point (x,y) and c.
Substitute these to find m.
Great! Now we have m and c and we can write the equation.
