For a straight line graph, the point at which the line crosses the y axis is called the y intercept. From the information given, the line crosses the y axis at - 5. This means that the y intercept is - 5
We would write the equation in the slope intercept form whicg is expressed as
y = mx + c
Where m represents the slpoe
We would substitute x = 2, y = 3 and c = - 5 in the equation above to determine the slope, m. It becomes
3 = m * 2 - 5
3 = 2m - 5
3 + 5 = 2m
2m = 8
m = 8/2
m = 4
The equation would be
y = 4x - 5y interceptF
