Answer:

Slope = 2/3

y-intercept = 1

The equation in slope intercept form is y = 2/3 x + 1

OR y = 2x/3 + 1

Explanation:

m is the slope. b is the y-intercept.

Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 2/3 and the y-intercept is +1

Step-by-step explanation: To find the slope, m, determine "rise over run"

Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (โ€“3,โ€“1), (0,1) and (3,3)

The "rise" is the difference in y-values. Here, they increase by 2.

The "run" is the difference in x-values. Here they increase by 3.

So the slope is 2/3. Put that in place of m in the equation

The graphed line crosses the y-axis at +1

That is the y-intercept. Use +1 in the place of b

Keep the y and x; substitute the values for m and b we found.

y = 2/3 x + 1

OR

y = 2/3+ 1 This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be multiplied by 2 and divided by 3.
