2. The line y = 4x - 7 crosses the y axis at:
(4, 0)
(0, 4)
(-7, 0)
(0, -7)
(0,-7). if u get a graphing calculator then u would be able to solve easily.
Set x=0 and solve for y to get
y = 4*0 - 7 = 0 - 7 so
y=7
The coordinate is (0,-7)
To find the point at which a line crosses the y-axis, you need to identify the y-coordinate when x equals 0. In this case, the given equation is y = 4x - 7.
To solve for the y-coordinate when x = 0, substitute 0 for x in the equation:
y = 4(0) - 7
y = 0 - 7
y = -7
Hence, the line y = 4x - 7 crosses the y-axis at (0, -7).
