Final answer:
The equation should be in the form y = mx + b to represent the slope-intercept form. After correcting the equation, it shows that y is already isolated, representing the slope 2/3 and the y-intercept as 4.
Step-by-step explanation:
The equation given seems to have a typo and should likely be in the form y = mx + b, where m is the slope and b is the y-intercept, which is known as the slope-intercept form. To solve for y in intercept form, which is actually the slope-intercept form, you would isolate y on one side of the equation. If we correct the equation to y = (2/3)x + 4, then it is already in slope-intercept form with a slope of 2/3 and a y-intercept of 4.
For example, the equation of the line of best fit given is ŷ = -173.51 + 4.83x, which is already in slope-intercept form with a slope of 4.83 and a y-intercept of -173.51.
