Answer:

y = -4x + 5.

Explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Given that the line passes through the point (2, -3) and has a slope of -4, we can use the point-slope form of a linear equation to find the y-intercept:

y - y1 = m(x - x1)

where x1 and y1 are the coordinates of the given point, and m is the slope.

Substituting the given values, we get:

y - (-3) = -4(x - 2)

Simplifying and rearranging, we get:

y + 3 = -4x + 8

Subtracting 3 from both sides, we get:

y = -4x + 5

Therefore, the equation in slope-intercept form for the given line is y = -4x + 5.
