Pls help me with these 2 math question will mark brainiest.

Answer:
3) B
4) A
Step-by-step explanation:
3)
Formula: [tex]y = mx + b[/tex]
Slope: [tex]\frac{-3 - 1}{-4 - (-2)} =2[/tex]
Next, I substituted the numbers from both the chart and the slope.
[tex]y=2x+b[/tex]
[tex](x, y) --> (1, 7)[/tex]
[tex]\\7=2(1)+b\\[/tex]
[tex]7=2+b[/tex]
[tex]b=5\\[/tex]
Your final equation should be, [tex]y=2x+5[/tex].
4)
From the graph you can see (0, 4) is the y-intercept and the spaces are moving up twice and once to the right, making the slope 2.
Your answer should be, [tex]y=2x+4[/tex].
