Answer: y=8/9x+0
Step 1: Determine the 2 points that will be used
(-9,-8)
(0,0)
Step 2: Starting with finding slope, write out the equation that you need to use
y2-y1/x2-x1
Step 3: Substitute the points into the equation and solve
0- -8/ 0- -9 = 8/9
*This will be the slope*
Step 4: Write out the equation in slope-intercept form
y= 8/9x+b
Step 4: To find the y-intercept, substitute y and x from a point and solve
y=8/9x+b
-8= 8/9 (-9) +b
-8= -8 +b
+8 +8
_______
0=b
*This will be the y-intercept*
Step 5: Replace b and m in the equation to get your final answer
y=mx+b
y=8/9x+0
