Answer:
y = 3x - 7
Explanation:
The slope is 3 and the y-intercept is -7
y = mx + b
y = 3x - 7
Slope:
The slope is when the x value is o. The point (0,3) tells us that the slope is 3.
y-intercept:
Use the x value 4 from the point given (4,5)
Use the y value 5 from the point given (4,5)
Use the slope given 3.
y = mx + b
5 = 3(4) + b
3 = 12 + b subtract 12 from both sides
3 - 12 = 12 - 12 + b
-7 = b
