Write an equation in point-slope from for a line that passes through the given set of points. (3,5) and (-6,-4)

Y-y1=m(x-x1)

does this help or do you need help plugging in and finding slope?

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
