Ch3L5 Graphing Equation

Question 1

how to graph a linear equation in slope-intercept form

Answer 1

Step 1: using y-intercept to find the intersection point of the line and y-axiels. This is the first point P1 you get for the line. Step 2:Using the slope to get change of y in accordance to change of x. so if x change 1 unit then you change m unit. so start from the first point, move x and y steps to get your second point. P2 Step 3:Connect P1 and P2 to get the line

how to graph it?

Question 22

If a line passes through the original point(0,0), so it should be represented as:

y = mx + b

or

y= mx

Question 23

how to find the intersect point of line and y-Axis?

Answer 23

We can use y-intercept to find the intersect between this line and y-Axis. The coordinates of this intersect point is(0,b) ,here b is the y-intercept.
