The slope-intercept form of an equation is y mx b which defines a line. Connect the points with a line. Where n n is called the index a a is called the radicand and the symbol is called the radical.
You can use the slope-intercept formula y mx b to identify the slope and intercept of the regression line. Learn to find the slope and y-intercept of the equation of a line plotted on a graph with this pdf worksheet prepared for 7th and 8th grade students. If a line has no y-intercept that means it never intersects the y-axis so it must be parallel to the y-axis.
We know from the question that our slope is 3 and our y-intercept is 5 so plugging these values in we get the equation of our line to be y 3x 5. M 3 and b 5. Identify the slope and y-intercept.
