Question

I need to find the slope-intercept form of this problem in the picture, please I need help!

Answer 1

y-int form is y=mx+b

First, let's find the slope, which is rise/run. From the first point to the second point, it goes up 3 and it goes to the right 4. Therefore the slope is 3/4

This is our equation so far:

`y= (3)/(4)x+b`

Now we can pick any point on the graph and substitute x and y. For this example, let's pick the second one. The coordinates for the second point in (x,y) is (1, 2) so plug 1 in x, 2 in y and solve for b.


`2= (3)/(4)1+b`

`2= (3)/(4)+b`

`2- (3)/(4)=b`

1.25=b

Therefore, the final answer is:

`y= (4)/(3)x+1.25`
