Translate this into an equation,

seven times the sum of a number and 4 is 2

7 x X + 4= 2
Why because x would be the variable that’s is added to 4

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
