Answer:
y=7x-4 intercept 4
Explanation:
Your friend made a mistake in the equation. The correct equation of a line with a slope of 7 that goes through the point (0, -4) is y = 7x - 4, not y = -4x + 7. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope and b represents the y-intercept. In this case, the slope is 7, so the equation should be y = 7x - 4, with a y-intercept of -4.
