Answer:

y = 1.5x + 0 or y = 1.5x

Step-by-step explanation:

=> First lets find the slope:

Slope: Change in y / Change in x

Change in y = +15

Change in x = 10

Slope = 15/10 or 1.5

=> Now lets find the, y-intercept:

We know that y-intercept is the y-value when x = 0

So we can say:

y = 1.5x

y = 1.5(0)

y = 0

Therefore y-intercept = 0

Final equation: y = 1.5x + 0 or y = 1.5x

Hope this helps!
