Question

Can someone help with this please?

Answer 1

y-intercept → (-5)

Slope → 4

Equation → y = 4x - 5

Explanation:

From the table attached,

y - intercept → Output value at x = 0

y = -5

Slope =
`(y_2-y_1)/(x_2-x_1)`

=
`(-13-(-9))/(-2-(-1))`

=
`(-13+9)/(-2+1)`

=
`(-4)/(-1)`

= 4

m = 4

Equation of a line is given by,

y = mx + b

Here, m = Slope

b = y-intercept

Therefore, equation of the line will be,

y = 4x + (-5)

y = 4x - 5
