Answer 1

Equation: y = 3x + 5

Slope: 3

Point: (-1, 2)

Explanation:

The line is going 5 units up in the y-axis, so therefore, our y-intercept is 5

thus, y = mx + 5

That's also a point on the graph so we can use (-1, 2) and (0, 5) to find the slope

m = slope

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

m =
`(5-2)/(0-(-1))`

m =
`(3)/(1)`

m = 3

The slope is 3

Thus, the equation is y = 3x + 5
