Looks like we’re doing slope intercept for this problem, there are no instructions but I’ve did and helped countless slope intercept problems.
So the equation for slope intercept is:
y=mx+b
m is the slope, rise/run, up and right is positive, down and left is negative. b is the y-intercept, where the line crosses the y-axis.
Let’s do the top one first. The line crosses the y-intercept at 3.5, or 3 1/2. So that’s b. Now for the slope. Let’s find two perfect points. (-3,3) and (4,4). Count how many units you have to rise and run to get to the other point, so from (-3,3) to (4,4). I counted 1 up and right 7. So the slope is 1/7. Now let’s put it in y=mx+b. You should get y=1/7x+3.5. That’s the equation for the top one.
Now let’s do the bottom one, same steps. y-intercept is -3. So b=-3. Two perfect points are (-5,-1) and (0,-3). Count from the first point to second point. I counted 2 down, 5 right. So the slope is -2/5. Put that in the equation and you should get y=-2/5x-3.
Hope this helped!
