Answer: at 5
Step-by-step explanation: the 3 is the slope and the 5 is the y intercept. The y-intercept corresponds to the value of 5 when the x value is equal to 0
Based on what we know about the formula of a straight line, the line above would cross the y-axis at 5.
The formula for a straight line takes the form:
y = mx + c
m = Gradient
c = y-intercept
The line described takes the form of y = 3x + 5.
5 is therefore c in the formula of a straight line so we can infer that it is the point where the y-axis is crossed.
In conclusion, the y-axis is crossed at 5.
