3. Draw the graph of the equation y = 3x - 4. Find
graphically
(i) the value of y when x = -1.
(ii) the value of x when y = 5.
4. Find the coordinates of the point where the
following lines cut the y-axis.
[Hint. A line cuts the y-axis where x 0.
Thus the line y = 2x + 5, will cut the y-axis at
y = 5, i.e., it will cut an intercept of 5 units from
the y-axis.]
(i) y = 5x + 1,
(ii) y = 3x - 7,
(iii) y = x + 5,
(iv) 3y = 2x + 9.
Please tell me the solution by graph

hey! here's ur answer
Answer:
3. (i) y value = -7
3. (ii) x value = 2
Step-by-step explanation:
3. (i) y= 3x - 4
y = 3×(-1) -4
y = -3 -4
y = -7
(ii) y = 3x-4
5 = 3x -4
4+5 = 3x
9 =3x
9/3 = x
2 = x
pls nobody delete this answer.. I'll report it, if it happens.
hope this answer helps you. I'll try solve the 4th one too
mark me as the brainlest if u like my answer)
